简单的lucene根据索引文件查询(搜索引擎)

                IndexReader reader = DirectoryReader.open(FSDirectory.open(new File("F:\\temp")));// 打开索引

IndexSearcher searcher = new IndexSearcher(reader);

Analyzer analyzer = new SmartChineseAnalyzer(Version.LUCENE_40);

String[] fields = { "questionname","id" };

Occur[] occurs = new Occur[] { Occur.SHOULD,Occur.SHOULD };

Query query =  MultiFieldQueryParser.parse(Version.LUCENE_40, " 测试 的", fields,

occurs, analyzer);

TopDocs result = searcher.search(query, searcher.getIndexReader()

.maxDoc());

ScoreDoc[] hits = result.scoreDocs;

List<Document> list = new ArrayList<Document>();

for (int i = 0; i <hits.length; i++) {

Document doc = searcher.doc(hits[i].doc);

list.add(doc);

}

System.out.println("搜索list的长度\t→→→→\t"+list.size());

for (Document document : list) {

System.out.println(document.getField("questionname"));

}

analyzer.close();

注：红色字体是输入的检索条件，多个用空格隔开，找到的结果先匹配同时符合多个的结果，结果只是拿过来的document一个list集合，具体结果再解析就行了。

结果如图：
