Luence 4.4 Jcseg分词器构建索引以及检索测试

一 利用Jcseg分词器构建索引

public class LuceneJcsegIndex {public static void main(String[] args) {String[] ids = new String[] { "1", "2", "3", "4" };String[] names = new String[] { "北京", "北京海淀", "南京", "shanghai" };String[] values = new String[] { "lang", "deg", "men", "context" };String[] bir = new String[] { "198108", "197906", "191111", "198710" };try {String dir = "D:\\user";// 目录Directory directory = new SimpleFSDirectory(new File(dir));Analyzer analyzer =  new JcsegAnalyzer4X(JcsegTaskConfig.COMPLEX_MODE);JcsegAnalyzer4X jcseg = (JcsegAnalyzer4X) analyzer;JcsegTaskConfig jcsegTaskConfig = jcseg.getTaskConfig();jcsegTaskConfig.setAppendCJKPinyin(true);jcsegTaskConfig.setAppendCJKSyn(true);IndexWriter indexWriter = new IndexWriter(directory,new IndexWriterConfig(Version.LUCENE_44, analyzer));for (int i = 0; i < ids.length; i++) {Document document = new Document();document.add(new IntField("id", Integer.parseInt(ids[i]),Store.YES));document.add(new StringField("name", names[i], Store.YES));document.add(new TextField("text", values[i], Store.YES));document.add(new StringField("datetime", bir[i], Store.YES));indexWriter.addDocument(document);}indexWriter.commit();indexWriter.close();} catch (NumberFormatException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

二 根据名称查询

Term term = new Term("name", "北京");

查询结果：

北京
lang
198108

三 测试QueryParse

package com.zsj.test;import java.io.File;import java.io.IOException;import org.apache.lucene.analysis.Analyzer;import org.apache.lucene.document.Document;import org.apache.lucene.index.IndexReader;import org.apache.lucene.queryparser.classic.ParseException;import org.apache.lucene.queryparser.classic.QueryParser;import org.apache.lucene.search.IndexSearcher;import org.apache.lucene.search.Query;import org.apache.lucene.search.ScoreDoc;import org.apache.lucene.search.TopDocs;import org.apache.lucene.store.Directory;import org.apache.lucene.store.FSDirectory;import org.apache.lucene.util.Version;import com.webssky.jcseg.core.JcsegTaskConfig;import com.webssky.jcseg.lucene.JcsegAnalyzer4X;/** * 测试Lucene 4.4简单搜索 *  * @author hadoop *  */public class LuceneJcsegQueryParse {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubString dir = "D:\\user";try {Directory directory = FSDirectory.open(new File(dir));@SuppressWarnings("deprecation")IndexReader reader = IndexReader.open(directory);IndexSearcher indexSearcher = new IndexSearcher(reader);/** * 创建搜索字段 */Analyzer analyzer = new JcsegAnalyzer4X(JcsegTaskConfig.COMPLEX_MODE);JcsegAnalyzer4X jcseg = (JcsegAnalyzer4X) analyzer;JcsegTaskConfig jcsegTaskConfig = jcseg.getTaskConfig();jcsegTaskConfig.setAppendCJKPinyin(true);jcsegTaskConfig.setAppendCJKSyn(true);QueryParser queryParser = new QueryParser(Version.LUCENE_44,"name", analyzer);//Test AND NOTQuery query = queryParser.parse("text:men AND NOT name:南京");//Test AND//Query query = queryParser.parse("text:men AND name:南京");// Term term = new Term("name", "北京");// TermQuery termQuery = new TermQuery(term);TopDocs topDocs = indexSearcher.search(query, 4);ScoreDoc scoreDocs[] = topDocs.scoreDocs;for (int i = 0; i < scoreDocs.length; i++) {Document document = indexSearcher.doc(scoreDocs[i].doc);System.out.println(document.get("id"));System.out.println(document.get("name"));System.out.println(document.get("text"));System.out.println(document.get("datetime"));}directory.close();} catch (IOException | ParseException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}
