Solr 中 Schema 结构说明

　　schema.xml位于solr/conf/目录下，类似于数据表配置文件，定义了加入索引的数据的数据类型，主要包括type、fields和其他的一些缺省设置

　　1、schema的基本配置

<?xml version="1.0" encoding="UTF-8" ?>
<schema name="user" version="1.6">
   <field name="_version_" type="long" indexed="true" stored="true"/>
   <field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
   <field name="name" type="text_general" indexed="true" stored="true"/>
   <uniqueKey>id</uniqueKey>

   <fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>
   <fieldType name="string" class="solr.StrField" sortMissingLast="true" />
   <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100" multiValued="true">
      <analyzer type="index">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
        <!-- in this example, we will only use synonyms at query time
        <filter class="solr.SynonymGraphFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
        <filter class="solr.FlattenGraphFilterFactory"/>
        -->
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
        <filter class="solr.SynonymGraphFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
    </fieldType>
</schema>
