solr4.7.2开发实践 ——拼音检索【需要用到的包pinyin4j-2.5.0.jar和pinyinAnalyzer.jar；只需要配置schema.xml文件、solrj的java代码测试】

  拼音检索的大致思路是这样的：

            ①将需要使用拼音检索的字段汇集到一个拼音分词字段里（我的拼音分词字段使用pinyin4j+NGram做的）；

                加入两个jar包：pinyin4j-2.5.0.jar、pinyinAnalyzer.jar；

                schema.xml文件设置：

<field name="pinyin" type ="text_pinyin" indexed ="true" stored ="false" multiValued ="true"/>
<copyField source="name" dest="pinyin"/>
 <copyField source="author" dest="pinyin"/>
 <copyField source="region" dest="pinyin"/>
 <copyField source="theme" dest="pinyin"/>
<!-- by michael: pinyin  -->
  <fieldType name="text_pinyin" class="solr.TextField" positionIncrementGap="0">
     <analyzer type="index">
     <tokenizer class="org.apache.lucene.analysis.cn.smart.SmartChineseSentenceTokenizerFactory"/>
     <filter class="org.apache.lucene.analysis.cn.smart.SmartChineseWordTokenFilterFactory"/>
     <filter class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory" minTermLenght="2" />
     <filter class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory" minGram="6" maxGram="20" />
     </analyzer>
     <analyzer type="query">
     <tokenizer class="org.apache.lucene.analysis.cn.smart.SmartChineseSentenceTokenizerFactory"/>
     <filter class="org.apache.lucene.analysis.cn.smart.SmartChineseWordTokenFilterFactory"/>
     <filter class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory" minTermLenght="2" />
     <filter class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory" minGram="6" maxGram="20" />
     </analyzer>
  </fieldType>

        ②使用solrj进行拼音检索：

/**
 * @method: testPhoneticize
 * @Description: 拼音检索
 *    ??? 也会把不符合条件的检索出来
 *    (解决方法：把汉子和相应的拼音建立同义词)
 * @return void
 *

 */
    public List<Map<String, String>> phoneticize(String pinyin){
  try {
   List<Map<String, String>> list = new ArrayList<Map<String, String>>();

   SolrQuery query = new SolrQuery();
   query.set("q", "pinyin:"+pinyin);//高亮查询字段

         QueryResponse qr=server.query(query);//执行查询
         SolrDocumentList dlist=qr.getResults();

         System.out.println("总数："+dlist.getNumFound());
         Map<String, String> mapRe = null;
         for(SolrDocument sd:dlist){
             mapRe = new HashMap<String, String>();
             mapRe.put("name", sd.getFieldValue("name").toString());
             mapRe.put("content", sd.getFieldValue("content").toString().substring(0,200));
             list.add(mapRe);
         }

         return list;
  } catch (SolrServerException e) {
   e.printStackTrace();
  }
  return null;
 }
