方法1:

 

Date starttime=new Date();String queryString = "o";String[] fields={"name","content"};QueryParser queryParser = new MultiFieldQueryParser(fields,analyzer);Query query=queryParser.parse(queryString);IndexSearcher indexSearcher=new IndexSearcher(INDEX_STORE_PATH);Filter filter=null;TopDocs topDocs=indexSearcher.search(query,filter,1000);Date endtime=new Date();System.out.println("共有"+(endtime.getTime()-starttime.getTime())+"ms");System.out.println("共有"+topDocs.totalHits+"个匹配结果");for(ScoreDoc scoreDoc : topDocs.scoreDocs){Document doc =indexSearcher.doc(scoreDoc.doc);System.out.println("content:"+doc.get("content"));System.out.println("name:"+doc.get("name"));System.out.println("path:"+doc.get("path"));}

运行结果:

 方法2:

 

starttime=new Date();IndexSearcher searcher = new IndexSearcher(INDEX_STORE_PATH);Term t = new Term("content", "o");Query q= new TermQuery(t);Hits h= searcher.search(q);endtime=new Date();long timeOfSearch = endtime.getTime()-starttime.getTime();System.out.println("共有"+timeOfSearch+"ms");System.out.println("共有"+h.length()+"个匹配结果");for(int i=0;i<h.length();i++){System.out.println(h.doc(i));System.out.println(h.doc(i).get("name"));System.out.println(h.score(i));System.out.println(h.id(i));}
