solr配置文件之solrconfig.xml

1.如果配置文件配置错误，是否提示。true要报错，false不报错。

 <abortOnConfigurationError>${solr.abortOnConfigurationError:true}</abortOnConfigurationError>

2.solr版本。

<luceneMatchVersion>LUCENE_31</luceneMatchVersion>

3. 索引文件目录，建索引的目录和查询的目录都是它。

<dataDir>${solr.data.dir:./solr/db/data}</dataDir>

4.一些基础配置

    4.1多少个document进行合并  

  <mergeFactor>10</mergeFactor>

    <!-- Sets the amount of RAM that may be used by Lucene indexing
         for buffering added documents and deletions before they are

         flushed to the Directory.  -->

   4.2 缓存大小

    <ramBufferSizeMB>32</ramBufferSizeMB>

多少个文档自动合并

 <mergeFactor>10</mergeFactor>

4.3.   

设置域的最大长度

<maxFieldLength>10000</maxFieldLength>

设置写锁的延迟时间
    <writeLockTimeout>1000</writeLockTimeout>

设置提交锁的延迟
    <commitLockTimeout>10000</commitLockTimeout>

4.4

 直接更新的方法：即调用solr默认的url访问。

 <updateHandler class="solr.DirectUpdateHandler2">

自动提交的最大文档数，最大时间

 <autoCommit> 
         <maxDocs>10000</maxDocs>
         <maxTime>1000</maxTime> 
       </autoCommit>

4.5包含所有查询的参数设置  <query>

设置lru缓存

    <filterCache class="solr.FastLRUCache"
                size="16384"
                          initialSize="4096"
                          autowarmCount="4096"/>

设置查询结果缓存

    <queryResultCache class="solr.LRUCache"
                      size="16384"
                                      initialSize="4096"
                                      autowarmCount="1024"/>

设置文档缓存
     <documentCache class="solr.LRUCache"
                   size="16384"
                               initialSize="16384"/>

是否延迟加载索引域

 <enableLazyFieldLoading>true</enableLazyFieldLoading>

设置查询的最大doc数

<queryResultMaxDocsCached>500</queryResultMaxDocsCached>

这个参数暂时未用

    <maxWarmingSearchers>2</maxWarmingSearchers>

假如用dataimport这solr自带的导入数据命令时，的参数，即与数据库对应的文件的位置

 <requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">  
    <lst name="defaults">  
      <str name="config">C:\solr-tomcat\solr\db\conf\db-data-config.xml</str>  
    </lst>  
  </requestHandler>  

这个标签是用来控制主索引服务器，与从索引服务器分发索引快照的所有属性的

     <requestHandler name="/replication" class="solr.ReplicationHandler" >
       <lst name="master">
         <str name="replicateAfter">commit</str>
         <str name="replicateAfter">startup</str>
         <str name="confFiles">schema.xml,stopwords.txt,elevate.xml</str>
         <str name="commitReserveDuration">00:00:60</str>
         <str name="httpBasicAuthUser">345</str>
         <str name="httpBasicAuthPassword">345</str>
       </lst>
     </requestHandler>

这个标签和他的名字是一样的，表示用于集群的组件所有参数

  <searchComponent name="clustering" 
                   enable="${solr.clustering.enabled:false}"
                   class="solr.clustering.ClusteringComponent" >
    <!-- Declare an engine -->
    <lst name="engine">
      <!-- The name, only one can be named "default" -->
      <str name="name">default</str>
      <!-- Class name of Carrot2 clustering algorithm. 
           
           Currently available algorithms are:
           
           * org.carrot2.clustering.lingo.LingoClusteringAlgorithm
           * org.carrot2.clustering.stc.STCClusteringAlgorithm
           
           See http://project.carrot2.org/algorithms.html for the
           algorithm's characteristics.
        -->
      <str name="carrot.algorithm">org.carrot2.clustering.lingo.LingoClusteringAlgorithm</str>
      <!-- Overriding values for Carrot2 default algorithm attributes.

           For a description of all available attributes, see:
           http://download.carrot2.org/stable/manual/#chapter.components.
           Use attribute key as name attribute of str elements
           below. These can be further overridden for individual
           requests by specifying attribute key as request parameter
           name and attribute value as parameter value.
        -->
      <str name="LingoClusteringAlgorithm.desiredClusterCountBase">20</str>
      
      <!-- The language to assume for the documents.
           
           For a list of allowed values, see:
           http://download.carrot2.org/stable/manual/#section.attribute.lingo.MultilingualClustering.defaultLanguage
       -->
      <str name="MultilingualClustering.defaultLanguage">ENGLISH</str>
    </lst>
    <lst name="engine">
      <str name="name">stc</str>
      <str name="carrot.algorithm">org.carrot2.clustering.stc.STCClusteringAlgorithm</str>
    </lst>
  </searchComponent>

当发生集群命令时，对应的相应参数。表示是否开启集群等。

 <requestHandler name="/clustering"
                  startup="lazy"
                  enable="${solr.clustering.enabled:false}"
                  class="solr.SearchHandler">
    <lst name="defaults">
      <bool name="clustering">true</bool>
      <str name="clustering.engine">default</str>
      <bool name="clustering.results">true</bool>
      <!-- The title field -->
      <str name="carrot.title">name</str>
      <str name="carrot.url">id</str>
      <!-- The field to cluster on -->
       <str name="carrot.snippet">features</str>
       <!-- produce summaries -->
       <bool name="carrot.produceSummary">true</bool>
       <!-- the maximum number of labels per cluster -->
       <!--<int name="carrot.numDescriptions">5</int>-->
       <!-- produce sub clusters -->
       <bool name="carrot.outputSubClusters">false</bool>
       
       <str name="defType">edismax</str>
       <str name="qf">
          text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0 manu^1.1 cat^1.4
       </str>
       <str name="q.alt">*:*</str>
       <str name="rows">10</str>
       <str name="fl">*,score</str>
    </lst>     
    <arr name="last-components">
      <str>clustering</str>
    </arr>
  </requestHandler>

默认查询条件

  <admin>
    <defaultQuery>*:*</defaultQuery>

    <!-- configure a healthcheck file for servers behind a
         loadbalancer

    <!--
       <healthcheck type="file">server-enabled</healthcheck>
