You say there's only one document and you added many. The line
IndexWriter writer = new IndexWriter(indexPath, new StandardAnalyzer(), true); blows away any existing index data and starts over. If you're calling this fragment for each document, you'll always have only one doc. Try changing the 'true' to 'false'. Or better yet, open the writer outside the document add routines and pass it in... I still have no clue why you're getting the results you are. StandardAnalyzer doesn't stem, so that's probably not it. Try query.toString() to see what the actual query you're submitting is. Then, I'd think about playing with that query in Luke to see what's happening. Best ErickOn 7/19/07, Ard Schrijvers <[EMAIL PROTECTED]> wrote:
Hello Askar, Which analyzer are you using for indexing and searching? If you use an analyzer that uses stemming, you might see that "change", "changing", "changed", "chan" etc al get reduced to the same word "chan". In luke you can test with plugins that show you what tokens are created from your analyzer, Regards Ard > > > Hey Guys, > > I just checked my Lucene results.
