拼音檢索的大致思路是這樣的:
①將需要使用拼音檢索的字段匯集到一個(gè)拼音分詞字段里(我的拼音分詞字段使用pinyin4j+NGram做的)
加入兩個(gè)jar包:pinyin4j-2.5.0.jar、pinyinAnalyzer.jar;
schema.xml文件設(shè)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進(jìn)行拼音檢索:
/** * @method: testPhoneticize * @Description: 拼音檢索 * ??? 也會(huì)把不符合條件的檢索出來(lái) * (解決方法:把漢子和相應(yīng)的拼音建立同義詞) * @return void * * @author: ChenYW * @date 2014-4-16 下午01:44:57 */ 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);//高亮查詢字段 QueryResponse qr=server.query(query);//執(zhí)行查詢 SolrDocumentList dlist=qr.getResults(); System.out.println("總數(shù):"+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; }
