You don't need to rewrite queries, its automatically done inside Lucene's search logic, just run the query with IndexSearcher.search. To what Lucene rewrites queries is internal and can change at any time.
So what is the problem? -- Uwe Schindler H.-H.-Meier-Allee 63, 28213 Bremen http://www.thetaphi.de S Eslamian <seslam...@gmail.com> schrieb: Thanks Ian for your answer. I'm using lucene 3.5. Let me say from the beginning : I've written a MyParser class which extends MultiFieldQueryParser. And then override the getRangeQuery method. In this method I call NumericRangeQuery.newIntRange for receiving the query. Then in my main method, I have a query like this : "field : [10 TO 20]". I call MyParser.parse with that query, then after receiving the parsed query, I call rewrite method : QueryParser qp = new MyQueryPrser (version,fields[],analyzer); Query q = qp.parse("field : [10 TO 20]"); IndesSearcher is = new IndexSearcher(IndexReader.open(NIOFSDirectory.open(new File("Index Address")))); Query rewrittenQuery = is.rewrite(q); The rewrittenQuery in some ranges is wrong and has a strange value!
