lucene使用方式

自己写了个小例子

package com.lucene.test;import java.io.File;import java.io.IOException;import org.apache.lucene.analysis.Analyzer;import org.apache.lucene.analysis.standard.StandardAnalyzer;import org.apache.lucene.document.Document;import org.apache.lucene.document.Field;import org.apache.lucene.document.Field.Store;import org.apache.lucene.index.CorruptIndexException;import org.apache.lucene.index.IndexWriter;import org.apache.lucene.index.IndexWriter.MaxFieldLength;import org.apache.lucene.queryParser.ParseException;import org.apache.lucene.queryParser.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.FSDirectory;import org.apache.lucene.store.LockObtainFailedException;public class IndexWriterTest {public static void main(String[] args) {try {File file = new File("d:/index");IndexWriter writer = new IndexWriter(file, new StandardAnalyzer(), MaxFieldLength.UNLIMITED);Document doc = new Document();//测试 lucene能否实现不同属性检索Field field = new Field("title", "测试lucene能否实现不同属性检索", Store.YES, Field.Index.ANALYZED, Field.TermVector.NO);doc.add(field);writer.addDocument(doc);doc = new Document();field = new Field("descript", "描述内容", Store.YES, Field.Index.ANALYZED, Field.TermVector.NO);doc.add(field);writer.addDocument(doc);writer.optimize();writer.close();//检索IndexSearcher search = new IndexSearcher(FSDirectory.getDirectory("d:/index"));Analyzer analyzer = new StandardAnalyzer();QueryParser parser = new QueryParser("descript", analyzer);Query query = parser.parse("描述");//BooleanQuery q = new BooleanQuery();//RangeQuery range = new RangeQuery(new Term("time", ""), new Term("time",""), false);TopDocs docs = search.search(query, 10);System.out.println("找到记录共"+docs.totalHits+"条。");ScoreDoc[] d = docs.scoreDocs;for(ScoreDoc s: d){int id = s.doc;Document dd = search.doc(id);System.out.println(dd.get("descript"));}} catch (CorruptIndexException e) {e.printStackTrace();} catch (LockObtainFailedException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (ParseException e) {e.printStackTrace();}}}
