lucene 是一个全文检索的纯java的工具，对中文分词支持不好，需要其他分词组件支持 如 ikanalysize , paoding ，je 等。

lucene 的基本流程，首先需要建立索引  index , 然后就是搜索索引 search 。

下面放出一个入门的例子

public void testIndexAndSearchold() throws CorruptIndexException, LockObtainFailedException, IOException, ParseException{
  Analyzer analyzer = new StandardAnalyzer();
// Store the index in memory:
Directory directory = new RAMDirectory();
// To store an index on disk, use this instead:
//Directory directory = FSDirectory.getDirectory("/tmp/testindex");
IndexWriter iwriter = new IndexWriter(directory, analyzer, IndexWriter.MaxFieldLength.LIMITED);
Document doc = new Document();
String text = "This is the text to be indexed.";
doc.add(new Field("fieldname", text, Field.Store.YES,
Field.Index.ANALYZED));
iwriter.addDocument(doc);
iwriter.optimize();
iwriter.close();
// Now search the index:
IndexSearcher isearcher = new IndexSearcher(directory);
// Parse a simple query that searches for "text":
QueryParser parser = new QueryParser("fieldname", analyzer);
Query query = parser.parse("text");
TopDocCollector hits = new TopDocCollector(0);
isearcher.search(query,hits);
assertEquals(1, hits.getTotalHits());
// Iterate through the results:
for (int i = 0; i < hits.getTotalHits(); i++) {
Document hitDoc = isearcher.doc(i);
assertEquals("This is the text to be indexed.", hitDoc.get("fieldname"));
}
isearcher.close();
directory.close();

}
