在Solr Schema.xml示例的示例中,我们将讨论Apache Solr提供的schema.xml文件中的不同配置参数。schema.xml描述了我们希望Solr索引的文档。 我们可以定义字段类型和字段本身。 字段类型定义很强大,包括有关Solr如何处理传入字段值和查询值的信息。我们将讨论如何创建字段,创建自定义字段类型,在此示例中使用复制字段和使用动态字段。
为了演示schema.xml文件的使用,我们将使用基本配置在Solr中创建一个核心,并索引与Solr安装一起提供的示例文件。
这个例子的首选环境是solr-5.0.0。在开始Solr安装之前,请确保已安装JDK并已正确设置Java_Home。
1.安装Apache Solr
首先,让我们从以下位置下载最新版本的Apache Solr:
http://lucene.apache.org/solr/downloads.html
Apache Solr已经经历了从4.xx到5.0.0的各种更改,因此如果您有不同版本的Solr,则需要下载5.xx版本以遵循此示例。
下载Solr zip文件后,将其解压缩到文件夹中。 提取的文件夹将如下所示:
bin
文件夹包含用于启动和停止服务器的脚本。 example
文件夹包含几个示例文件。 我们将使用其中一个来演示Solr如何对数据进行索引。server
文件夹包含用于写入所有Solr日志的logs
文件夹。在索引期间检查日志中的任何错误将有所帮助。 服务器下的solr
文件夹包含不同的集合或核心。 每个核/集合的配置和数据存储在相应的核/集合文件夹中。
Apache Solr附带了一个内置的Jetty服务器。 但在我们启动solr实例之前,我们必须验证JAVA_HOME是否在机器上设置。
我们可以使用命令行脚本启动服务器。 让我们从命令提示符转到bin目录并发出以下命令:
solr start
这将在默认端口8983下启动Solr服务器。
我们现在可以在浏览器中打开以下URL,并验证我们的Solr实例正在运行。 solr管理工具的具体细节超出了示例的范围。
http://localhost:8983/solr/
2.创建Solr核心
当Solr服务器在独立模式下启动时,配置称为核心,当在SolrCloud模式下启动时,配置称为集合。在这个例子中,我们将讨论独立的服务器和核心。 我们将暂停SolrCloud讨论以供日后使用。
首先,我们需要创建一个用于索引数据的Core。 Solr create命令有以下选项:
- -c - 要创建的核心或集合的名称(必需)。
- -d - 配置目录,在SolrCloud模式下有用。
- -n - 配置名称。 此默认值与核心或集合的名称相同。
- -p - 要向其发送create命令的本地Solr实例的端口;默认情况下,脚本尝试通过查找正在运行的Solr实例来检测端口。
- -s - 将集合拆分为的分片数,默认值为1。
- -rf - 集合中每个文档的副本数。默认值为1。
在本例中,我们将使用-c参数作为核心名称,使用-d参数作为配置目录。 对于所有其他参数,我们使用默认设置。
现在在命令窗口中导航solr-5.0.0\bin
文件夹,并发出以下命令:
solr create -c jcg -d basic_configs
我们可以在命令窗口中看到以下输出。
1 |
"notranslate" onmouseover= "_tipon(this)" onmouseout= "_tipoff()" >"google-src-text" style= "direction: ltr; text-align: left" >Creating new core 'jcg' using command : 使用命令创建新核心 'jcg' :
|
2 |
"notranslate" onmouseover= "_tipon(this)" onmouseout= "_tipoff()" >"google-src-text" style= "direction: ltr; text-align: left" >http://localhost:8983/solr/admin/cores?action=CREATE&name=jcg&instanceDir=jcg http:// localhost:8983 / solr / admin / cores?action = CREATE&name = jcg&instanceDir = jcg
|
4 |
"notranslate" onmouseover= "_tipon(this)" onmouseout= "_tipoff()" >"google-src-text" style= "direction: ltr; text-align: left" >{ {
|
5 |
"notranslate" onmouseover= "_tipon(this)" onmouseout= "_tipoff()" >"google-src-text" style= "direction: ltr; text-align: left" > "responseHeader" :{ “responseHeader”:{
|
6 |
"notranslate" onmouseover= "_tipon(this)" onmouseout= "_tipoff()" >"google-src-text" style= "direction: ltr; text-align: left" > "status" :0, “status”:0,
|
7 |
"notranslate" onmouseover= "_tipon(this)" onmouseout= "_tipoff()" >"google-src-text" style= "direction: ltr; text-align: left" > "QTime" :663}, “QTime”:663},
|
8 |
"notranslate" onmouseover= "_tipon(this)" onmouseout= "_tipoff()" >"google-src-text" style= "direction: ltr; text-align: left" > "core" : "jcg" } “core”:“jcg”}
|
现在我们导航到以下URL,我们可以看到jcg core被填充在核心选择器中。 您还可以查看核心的统计信息。
http://localhost:8983/solr
3.使用字段类型
我们需要修改文件夹server\solr\jcg\conf
下的schema.xml
文件,以包含字段。我们将使用随同Solr安装一起提供的示例文件“books.csv”中的一个进行索引。 该文件位于文件夹solr-5.0.0\example\exampledocs
现在我们导航到文件夹server\solr
目录。 您将看到一个名为jcg
的文件夹。 子文件夹即conf
和data
分别具有核心的配置和索引数据。
现在编辑\server\solr\jcg\conf
文件夹中的schema.xml文件,并在uniqueKey元素后面添加以下内容。
schema.xml
1 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< uniqueKey >id uniqueKey > span > < uniqueKey > id uniqueKey > span > |
2 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >
span > <! - 为books.csv加载添加的字段 - > span > |
3 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "cat" type = "text_general" indexed = "true" stored = "true" /> span > < field name =“cat”type =“text_general”indexed =“true”stored =“true”/> span > |
4 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "name" type = "text_general" indexed = "true" stored = "true" /> span > < field name =“name”type =“text_general”indexed =“true”stored =“true”/> span > |
5 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "price" type = "tdouble" indexed = "true" stored = "true" /> span > < field name =“price”type =“tdouble”indexed =“true”stored =“true”/> span > |
6 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "inStock" type = "boolean" indexed = "true" stored = "true" /> span > < field name =“inStock”type =“boolean”indexed =“true”stored =“true”/> span > |
7 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "author" type = "text_general" indexed = "true" stored = "true" /> span > < field name =“author”type =“text_general”indexed =“true”stored =“true”/> span > |
我们已将indexed
的属性设置为true。 这指定了用于索引的字段,并且可以使用索引检索记录。 将值设置为false将使该字段只存储,但不能查询。
还要注意,我们有另一个属性叫stored
并设置为true。 这指定字段存储并可以在输出中返回。 将此字段设置为false将使该字段仅编入索引,并且无法在输出中检索。
我们已经为“books.csv”文件中的字段分配了类型。 CSV文件“id”中的第一个字段由schema.xml文件的uniqueKey元素自动处理,用于建立索引。
4.定义字段类型
在创建核心时,默认情况下会创建许多字段类型。 字段类型定义了Solr应如何解释字段中的数据以及如何查询字段。 我们将创建一个字段类型“ text_uppercase”,它将数据转换为大写字母值并对其进行索引。 字段类型定义可以包括四种类型的信息:
- 实现类名称(强制)
- 字段类型的名称(强制)
- 如果字段类型为TextField,则说明字段类型的字段分析
- 字段类型属性 - 根据实现类,一些属性可能是必需的。
字段类型确定字段类型的大多数行为,但也可以定义可选属性。
现在编辑\server\solr\jcg\conf
文件夹中的schema.xml文件,并在小写字段类型后添加以下内容。以下配置将创建一个字段类型“text_uppercase”。
schema.xml
01 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >
span > - > span > |
02 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< fieldType name = "lowercase" class = "solr.TextField" positionIncrementGap = "100" > span > < fieldType name =“lowercase”class =“solr.TextField”positionIncrementGap =“100”> span > |
03 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< analyzer > span > < analyzer > span > |
04 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< tokenizer class = "solr.KeywordTokenizerFactory" /> span > < tokenizer class =“solr.KeywordTokenizerFactory”/> span > |
05 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< filter class = "solr.LowerCaseFilterFactory" /> span > < filter class =“solr.LowerCaseFilterFactory”/> span > |
06 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" > analyzer > span > analyze > span > |
07 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" > fieldType > span > fieldType > span > |
08 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< fieldType name = "text_uppercase" class = "solr.TextField" positionIncrementGap = "100" > span > < fieldType name =“text_uppercase”class =“solr.TextField”positionIncrementGap =“100”> span > |
09 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< analyzer > span > < analyzer > span > |
10 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< tokenizer class = "solr.WhitespaceTokenizerFactory" /> span > < tokenizer class =“solr.WhitespaceTokenizerFactory”/> span > |
11 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< filter class = "solr.UpperCaseFilterFactory" /> span > < filter class =“solr.UpperCaseFilterFactory”/> span > |
12 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" > analyzer > span > analyze > span > |
13 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" > fieldType > span > fieldType > span > |
5.使用复制字段
复制字段命令将文档添加到索引时将一个字段复制到另一个字段。 它用于以不同方式对同一字段建立索引,或者将多个字段添加到同一字段,以便更容易/更快速地搜索。
在我们的示例中,我们将为名称创建一个复制字段。 我们将使用复制字段以大写形式对名称建立索引。
现在编辑\server\solr\jcg\conf
文件夹中的schema.xml文件,并在小写字段类型后添加以下内容。以下配置将创建一个字段类型“text_uppercase”。
schema.xml
1 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >
span > - > span > |
5 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< copyField source = "name" dest = "uname" /> span > < copyField source =“name”dest =“uname”/> span > |
现在我们必须将字段类型分配给目标。 我们将字段类型添加为“text_uppercase”,如下所示。
schema.xml
1 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< uniqueKey >id uniqueKey > span > < uniqueKey > id uniqueKey > span > |
2 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >
span > <! - 为books.csv加载添加的字段 - > span > |
3 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "cat" type = "text_general" indexed = "true" stored = "true" /> span > < field name =“cat”type =“text_general”indexed =“true”stored =“true”/> span > |
4 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "name" type = "text_general" indexed = "true" stored = "true" /> span > < field name =“name”type =“text_general”indexed =“true”stored =“true”/> span > |
5 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "price" type = "tdouble" indexed = "true" stored = "true" /> span > < field name =“price”type =“tdouble”indexed =“true”stored =“true”/> span > |
6 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "inStock" type = "boolean" indexed = "true" stored = "true" /> span > < field name =“inStock”type =“boolean”indexed =“true”stored =“true”/> span > |
7 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "author" type = "text_general" indexed = "true" stored = "true" /> span > < field name =“author”type =“text_general”indexed =“true”stored =“true”/> span > |
8 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< field name = "uname" type = "text_uppercase" indexed = "true" stored = "true" /> span > < field name =“uname”type =“text_uppercase”indexed =“true”stored =“true”/> span > |
6.使用动态字段
动态字段通过在配置原理上应用约定来创建。 当我们使用基本配置创建核心时,默认情况下会创建以下动态字段。
schema.xml
01 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_i" type = "int" indexed = "true" stored = "true" /> span > < dynamicField name =“* _ i”type =“int”indexed =“true”stored =“true”/> span > |
02 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_is" type = "int" indexed = "true" stored = "true" multiValued = "true" /> span > < dynamicField name =“* _ is”type =“int”indexed =“true”stored =“true”multiValued =“true”/> span > |
03 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_s" type = "string" indexed = "true" stored = "true" /> span > < dynamicField name =“* _ s”type =“string”indexed =“true”stored =“true”/> span > |
04 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_ss" type = "string" indexed = "true" stored = "true" multiValued = "true" /> span > < dynamicField name =“* _ ss”type =“string”indexed =“true”stored =“true”multiValued =“true”/> span > |
05 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_l" type = "long" indexed = "true" stored = "true" /> span > < dynamicField name =“* _ l”type =“long”indexed =“true”stored =“true”/> span > |
06 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_ls" type = "long" indexed = "true" stored = "true" multiValued = "true" /> span > < dynamicField name =“* _ ls”type =“long”indexed =“true”stored =“true”multiValued =“true”/> span > |
07 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_t" type = "text_general" indexed = "true" stored = "true" /> span > < dynamicField name =“* _ t”type =“text_general”indexed =“true”stored =“true”/> span > |
08 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_txt" type = "text_general" indexed = "true" stored = "true" multiValued = "true" /> span > < dynamicField name =“* _ txt”type =“text_general”indexed =“true”stored =“true”multiValued =“true”/> span > |
09 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_en" type = "text_en" indexed = "true" stored = "true" multiValued = "true" /> span > < dynamicField name =“* _ en”type =“text_en”indexed =“true”stored =“true”multiValued =“true”/> span > |
10 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_b" type = "boolean" indexed = "true" stored = "true" /> span > < dynamicField name =“* _ b”type =“boolean”indexed =“true”stored =“true”/> span > |
11 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_bs" type = "boolean" indexed = "true" stored = "true" multiValued = "true" /> span > < dynamicField name =“* _ bs”type =“boolean”indexed =“true”stored =“true”multiValued =“true”/> span > |
12 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_f" type = "float" indexed = "true" stored = "true" /> span > < dynamicField name =“* _ f”type =“float”indexed =“true”stored =“true”/> span > |
13 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_fs" type = "float" indexed = "true" stored = "true" multiValued = "true" /> span > < dynamicField name =“* _ fs”type =“float”indexed =“true”stored =“true”multiValued =“true”/> span > |
14 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_d" type = "double" indexed = "true" stored = "true" /> span > < dynamicField name =“* _ d”type =“double”indexed =“true”stored =“true”/> span > |
15 |
< span class = "notranslate" onmouseover = "_tipon(this)" onmouseout = "_tipoff()" >< span class = "google-src-text" style = "direction: ltr; text-align: left" >< dynamicField name = "*_ds" type = "double" indexed = "true" stored = "true" multiValued = "true" /> span > < dynamicField name =“* _ ds”type =“double”indexed =“true”stored =“true”multiValued =“true”/> span > |
在books.csv文件中,我们有以下字段动态映射到字段类型。
- series_t - 映射到动态字段名称“* _t”并分配类型text_general
- sequence_i - 映射到动态字段名称“* _i”,并分配类型int
- genre_s - 映射到动态字段名称“* _s”并分配类型字符串
7.索引数据
Apache Solr附带一个名为SimplePostTool的独立Java程序。 该程序打包到JAR中,安装在example\exampledocs
文件夹下。
现在,我们导航到命令提示符中的example\exampledocs
文件夹,并键入以下命令。您将看到一堆使用该工具的选项。
java -jar post.jar -h
使用格式一般如下:
Usage: java [SystemProperties] -jar post.jar [-h|-] [
[...]]
正如我们前面所说,我们将索引solr安装附带的“books.csv”文件中的数据。 我们将在命令提示符中导航到solr-5.0.0\example\exampledocs
并发出以下命令。
java -Dtype=text/csv -Durl=http://localhost:8983/solr/jcg/update -jar post.jar books.csv
这里使用的SystemProperties是:
- -Dtype - 数据文件的类型。
- -Durl - jcg核心的URL。
文件“books.csv”现在将被索引,并且命令提示符将显示以下输出。
1 |
"notranslate" onmouseover= "_tipon(this)" onmouseout= "_tipoff()" >"google-src-text" style= "direction: ltr; text-align: left" >SimplePostTool version 5.0.0 SimplePostTool版本5.0.0
