(九)solr实现autocomplete功能

autocomplete 是什么相信你懂的，真的不知道的话，那就问百度吧

直接上配置

schema.xml

 <field name="id"     type="string"   indexed="true"  stored="true"  required="true"/>
 <field name="title" type="text" indexed="true" stored="true"/>

类型定义：

   <fieldtype name="string"  class="solr.StrField" sortMissingLast="true" omitNorms="true"/>
   <fieldtype name="text" class="solr.TextField">
    <analyzer>
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>

solrconfig.xml

<searchComponent class="solr.SpellCheckComponent" name="suggester">
    <lst name="spellchecker">
    <str name="name">suggester</str>
    <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
    <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
    <str name="field">title</str>
    <float name="threshold">0.01</float>
    <str name="buildOnCommit">true</str>
    </lst>
</searchComponent>

<requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggester">
    <lst name="defaults">
    <str name="spellcheck">true</str>
    <str name="spellcheck.dictionary">suggester</str>
    <str name="spellcheck.count">10</str>
    </lst>
    <arr name="components">
    <str>suggester</str>
    </arr>
</requestHandler>

通过下面的方式，测试结果：

http://localhost:8983/solr/suggester/?q=%E8%BF%99%E6%98%AF

<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">0</int>
</lst>
<lst name="spellcheck">
<lst name="suggestions">
<lst name="这是">
  <int name="numFound">2</int>
  <int name="startOffset">0</int><int name="endOffset">2</int>
  <arr name="suggestion">
  <str>这是什么标题呢</str>
  <str>这是测试文章</str>
  </arr>
</lst>
</lst>
</lst>
</response>
