Lucence使用笔记

1. lucence分页

1. TopScoreDocCollector topCollector = TopScoreDocCollector.create(  
2.                     100, false);          
3. searcher.search(query, topCollector);  
4. System.out.println("命中：" + topCollector.getTotalHits());  
5.  // 查询当页的记录    
6. ScoreDoc[] docs = topCollector.topDocs((pageNO - 1) * pageSize,  
7.                     pageSize).scoreDocs;；

2. 多字段排序使用org.apache.lucene.search.TopFieldCollector

3.高亮显示格式化查询结果：

 

SimpleHTMLFormatter simpleHTMLFormatter = new SimpleHTMLFormatter("<b><font color='red'>", "</font></b>"); 

Highlighter highlighter = new Highlighter(simpleHTMLFormatter, new QueryScorer(query));  

highlighter.setTextFragmenter(new SimpleFragmenter(Integer.MAX_VALUE))

TokenStream tokenStream = getAnalyzer().tokenStream(FIELD_TITLE, new StringReader(value));  
                    String str = highlighter.getBestFragment(tokenStream, value); 

System.out.println(str);
