<!--  
 This is the Solr schema file. This file should be named "schema.xml" and
 should be in the conf directory under the solr home
 (i.e. ./solr/conf/schema.xml by default) 
 or located where the classloader for the Solr webapp can find it.

 This example schema is the recommended starting point for users.
 It should be kept correct and concise, usable out-of-the-box.

 For more information, on how to customize this file, please see
 http://wiki.apache.org/solr/SchemaXml

 PERFORMANCE NOTE: this schema includes many optional features and should not
 be used for benchmarking.  To improve performance one could
  - set stored="false" for all fields possible (esp large fields) when you
    only need to search on the field but don't need to return the original
    value.
  - set indexed="false" if you don't need to search on the field, but only
    return the field as a result of searching on other indexed fields.
  - remove all unneeded copyField statements
  - for best index size and searching performance, set "index" to false
    for all general text fields, use copyField to copy them to the
    catchall "text" field, and use that for searching.
  - For maximum indexing performance, use the StreamingUpdateSolrServer
    java client.
  - Remember to run the JVM in server mode, and use a higher logging level
    that avoids logging every request

  <!-- attribute "name" is the name of this schema and is only used for display purposes.

       not normally be changed by applications.
       1.0: multiValued attribute did not exist, all fields are multiValued by nature
       1.1: multiValued attribute introduced, false by default 
       1.2: omitTermFreqAndPositions attribute introduced, true by default except for text fields.
       1.3: removed optional field compress feature
       1.4: default auto-phrase (QueryParser feature) to off
       1.5: omitNorms defaults to true for primitive field types (int, float, boolean, string...)

      <!-- Kuromoji Japanese morphological analyzer/tokenizer (JapaneseTokenizer)

           Kuromoji has a search mode (default) that does segmentation useful for search.  A heuristic
           is used to segment compounds into its parts and the compound itself is kept as synonym.

           Valid values for attribute mode are:
              normal: regular segmentation
              search: segmentation useful for search with synonyms compounds (default)
            extended: same as search mode, but unigrams unknown words (experimental)

           For some applications it might be good to use search mode for indexing and normal mode for
           queries to reduce recall and prevent parts of compounds from being matched and highlighted.
           Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query.

           Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
           model with your own entries for segmentation, part-of-speech tags and readings without a need
           to specify weights.  Notice that user dictionaries have not been subject to extensive testing.

           User dictionary attributes are:
                     userDictionary: user dictionary filename
             userDictionaryEncoding: user dictionary encoding (default is UTF-8)

           See lang/userdict_ja.txt for a sample user dictionary file.

<!--  //Introduction to the schema.xml file 
 This is the Solr schema file. This file should be named "schema.xml" and
 should be in the conf directory under the solr home
 (i.e. ./solr/conf/schema.xml by default) 
 or located where the classloader for the Solr webapp can find it.

 This example schema is the recommended starting point for users.
 It should be kept correct and concise, usable out-of-the-box.

 For more information, on how to customize this file, please see
 http://wiki.apache.org/solr/SchemaXml

 PERFORMANCE NOTE: this schema includes many optional features and should not
 be used for benchmarking.  To improve performance one could
 //提高性能的的选项设置
  - set stored="false" for all fields possible (esp large fields) when you
    only need to search on the field but don't need to return the original
    value. //只建索引的field （只索引，不存储）
    
  - set indexed="false" if you don't need to search on the field, but only
    return the field as a result of searching on other indexed fields.
    //只作为查询结果的返回的（只存储，不索引）
    
  - remove all unneeded copyField statements //去除所有不必要的备份字段（field）
  - for best index size and searching performance, set "index" to false
    for all general text fields, use copyField to copy them to the
    catchall "text" field, and use that for searching. 
    //对所有的的文本字段（不索引）而是将它们整合到一个文本杂项（cathall field),通过copyField实现
    //可以获得最好的索引量（index size）和搜索性能（search performace）
    
  - For maximum indexing performance, use the StreamingUpdateSolrServer
    java client.//使用StreamUpdateSolrServer java client 可以获得最优的建索引性能
    
  - Remember to run the JVM in server mode, and use a higher logging level
    that avoids logging every request //jvm server mode，logging level的设置
-->
 <!-- schema.xml 主要对应的document的字段的相关信息（字段的类型，字段的备份，多值查询）
 	A document is a collection of fields. 一个文档时相关字段的集合。
  schema.xml也是xml文件，而xml文件的一个中dom（document object model）,是一种树形文档结构。
  其根节点是schema，两个主要的子节点types、fields (还有 uniqueKey、copyField等)
  types节点中,通过solr中推过的java类，定义类型（type），该type将作为命名field的类型;
  fields中定义field，这些fields是solr为文档建index的依据，也是solr查询的依据；
  可以为文档类型(TextField)的field提供Ananlyzer(分析器)， 
  一个Analyzer是由一个个Tokenizer(分词器) 和多个TokenFilter(过滤器)组成;
  可以为TextField类型的Field的index 和 search 提供不同的Analyzer;

   <!-- Valid attributes for fields:
     name: mandatory - the name for the field
     type: mandatory - the name of a field type from the 
       <types> fieldType section
     indexed: true if this field should be indexed (searchable or sortable)
     stored: true if this field should be retrievable
     multiValued: true if this field may contain multiple values per document
     omitNorms: (expert) set to true to omit the norms associated with
       this field (this disables length normalization and index-time
       boosting for the field, and saves some memory).  Only full-text
       fields or fields that need an index-time boost need norms.
       Norms are omitted for primitive (non-analyzed) types by default.
     termVectors: [false] set to true to store the term vector for a
       given field.
       When using MoreLikeThis, fields used for similarity should be
       stored for best performance.
     termPositions: Store position information with the term vector.  
       This will increase storage costs.
     termOffsets: Store offset information with the term vector. This 
       will increase storage costs.
     required: The field is required.  It will throw an error if the
       value does not exist
     default: a value that should be used if no value is specified
       when adding a document.

         http://www.w3.org/TR/xmlschema-2/#dateTime

               NOW/HOUR
                  ... Round to the start of the current hour

      <!-- Kuromoji Japanese morphological analyzer/tokenizer (JapaneseTokenizer)

           Kuromoji has a search mode (default) that does segmentation useful for search.  A heuristic
           is used to segment compounds into its parts and the compound itself is kept as synonym.

           Valid values for attribute mode are:
              normal: regular segmentation
              search: segmentation useful for search with synonyms compounds (default)
            extended: same as search mode, but unigrams unknown words (experimental)

           For some applications it might be good to use search mode for indexing and normal mode for
           queries to reduce recall and prevent parts of compounds from being matched and highlighted.
           Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query.

           Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
           model with your own entries for segmentation, part-of-speech tags and readings without a need
           to specify weights.  Notice that user dictionaries have not been subject to extensive testing.

           User dictionary attributes are:
                     userDictionary: user dictionary filename
             userDictionaryEncoding: user dictionary encoding (default is UTF-8)

           See lang/userdict_ja.txt for a sample user dictionary file.

           See http://wiki.apache.org/solr/JapaneseLanguageSupport for more on Japanese language support.
