lucene分页查询

//创建indexsearcher对象

String ipath = PropertiesUtils.getPropertiesName(Const.SYSTEMCONFIG,"fileIndexPath"); IndexReader reader = DirectoryReader.open(FSDirectory.open(new File(ipath))); IndexSearcher  titleSearcher = new IndexSearcher(reader);

//创建query对象

BooleanQuery bquery = new BooleanQuery();

//排序

Sort s = new Sort(new SortField("pubDateFors", Type.INT, true));

TopFieldCollector c = TopFieldCollector.create(s, pageNum * pageSize,false, false, false, false);

searcher.search(query, c);

//分页查询结果

ScoreDoc[] hits = c.topDocs((pageNum - 1) * pageSize, pageSize).scoreDocs;

//查询结果总数

int hitCnt = c.topDocs().totalHits;

Document doc;

//查询结果转化成实体类 for (int i = 0; i < hits.length; i++) { FileBean bean = new FileBean(); doc = searcher.doc(hits[i].doc); bean.setId(doc.get("id"));

       bean.setFileName(doc.get("fileName"));
