solr4.7开发实践——拼音检索思路及代码实现
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
*
* @author: ChenYW

*/
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;
}
