  20  This is the Solr schema file. This file should be named "schema.xml" and
  21  should be in the conf directory under the solr home
  22  (i.e. ./solr/conf/schema.xml by default) 
  23  or located where the classloader for the Solr webapp can find it.
  24 
  25  This example schema is the recommended starting point for users.
  26  It should be kept correct and concise, usable out-of-the-box.
  27

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

  54             by nature
  55        1.1: multiValued attribute introduced, false by default 
  56        1.2: omitTermFreqAndPositions attribute introduced, true by default 
  57             except for text fields.
  58        1.3: removed optional field compress feature
  59        1.4: autoGeneratePhraseQueries attribute introduced to drive QueryParser

  67    <!-- Valid attributes for fields:
  68      name: 必填-字段的名称
  69      type: 必填- 字段的类型,来源于<fieldType>部分
  70      indexed: 是否被索引,只有设置为true的字段才能进行搜索排序
  71      stored: 是否存储内容,如果不需要存储字段值,尽量设置为false以提高效率
  72      docValues: DocValues从Lucene4.2和Solr4.2开始加入,通过建立字段的正排索引(设置为true),提升sorting, faceting, grouping, function queries等性能。
  73             虽然没有必要,doc values 将使得索引更快加载,更加友好,效率更高。然而,它们配备了一些限制,
  74             它们目前仅支持StrField,UUIDField 和所有的Trie*Fields,并且根据字段类型,它们可能需要这个
  75             字段是单值(single-value),必填或者有一个默认值(检查你感兴趣的字段类型的文档了解更多信息)
  76      multiValued: 是否为多值类型,SOLR允许配置多个数据源字段存储到一个搜索字段中。多个值选项必须为true,否则有可能抛出异常。
  77      termVectors: 默认为false,当设置true,会存储 term vector。当使用MoreLikeThis,用来作为相似词的field应该存储起来。
  78      termPositions: 存储 term vector中的地址信息,会消耗存储开销
  79      termOffsets: 存储 term vector 的偏移量,会消耗存储开销。
  80      required: 必填,如果不填则会报错。
  81      default: 默认值,如果没有属性需要修改,就可以用这个标识下。

1033 
1034            Kuromoji has a search mode (default) that does segmentation useful for search.  A heuristic
1035            is used to segment compounds into its parts and the compound itself is kept as synonym.
1036 
1037            Valid values for attribute mode are:
1038               normal: regular segmentation
1039               search: segmentation useful for search with synonyms compounds (default)
1040             extended: same as search mode, but unigrams unknown words (experimental)
1041 
1042            For some applications it might be good to use search mode for indexing and normal mode for
1043            queries to reduce recall and prevent parts of compounds from being matched and highlighted.
1044            Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query.
1045 
1046            Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
1047            model with your own entries for segmentation, part-of-speech tags and readings without a need
1048            to specify weights.  Notice that user dictionaries have not been subject to extensive testing.
