After some more testing, it seems the special characters in the url are causing problems.
The url field is stored un_tokenized, so the analyzer in use shouldn't matter? And in my original question, "contentlength" and "length" were indeed only errors in that post, the actual code contains the correct field names. Thanks for the ideas so far. At this point, I've tried using QueryParser.Parse and QueryParser.Escape. I've also tried adding quotes around the url: url:"http://some.website.com/"; Neither method gives the results I expect. Is there some way to have a look at what luke does to a query under the hood? -----Original Message----- From: Mark Cottman-Fields [mailto:mar...@qpac.com.au] Sent: Sunday, January 11, 2009 11:57 PM To: lucene-net-user@incubator.apache.org Subject: difference between Luke search and Lucene.Net search? Hi All I'm currently testing a lucene.net index for a website. The Luke search utility and my C# code give me different results for searches. There's probably a simple explanation, but I can't find it. The idea here is to check for changes using the url and the content length. C# code: (searcher is Lucene.Net.Search.IndexSearcher instance) public bool IsIndexed(Uri url, int stringcontent) { int foundCount = 0; Lucene.Net.Search.BooleanQuery bq = new Lucene.Net.Search.BooleanQuery(); bq.Add(new Lucene.Net.Search.TermQuery(new Lucene.Net.Index.Term("url", "\"" + url.AbsoluteUri + "\"")), Lucene.Net.Search.BooleanClause.Occur.MUST); bq.Add(new Lucene.Net.Search.TermQuery(new Lucene.Net.Index.Term("length", stringcontent.ToString())), Lucene.Net.Search.BooleanClause.Occur.MUST); Lucene.Net.Search.Hits hits = searcher.Search(bq); foundCount = hits.Length(); return foundCount > 0; } A search like: +url:"http://some.website.com/"; +contentlength:1234 Finds exactly one item in Luke (the expected behaviour, if the url is indexed and has that length exactly), but returns nothing in my code above. They are both using the same index. Any ideas? BTW, great project, thank you!
