> A.R --> The scenario is if I try search a text "Test&&Test" But the query "Test&&Test" will also be parsed as "test test" by StandardAnalyzer. Since there are 2 sucessive "test"s in the index, there must be a hit. DIGY -----Original Message----- From: Granroth, Neal V.

As in this simple example: StandardAnalyzer aa = new StandardAnalyzer(); System.IO.StringReader srs = new System.IO.StringReader("aaa bbb test&&test ccc ddd"); Lucene.Net.Analysis.TokenStream ts = aa.TokenStream(srs); Lucene.Net.Analysis.Token tk; while( (tk = ts.Next()) != null ) { System.Console.WriteLine(String.Format("Token: \"{0}\": S:{1}, E:{2}", tk.TermText(),tk.StartOffset(),tk.EndOffset())); } The output looks like this: Token: "aaa": S:0, E:3 Token: "bbb": S:4, E:7 Token: "test": S:8, E:12 Token: "test": S:14, E:18 Token: "ccc": S:19, E:22 Token: "ddd": S:23, E:26 You can see that the "&&" characters were identified as separators and two "test" tokens were emitted not the single "test&&test" you expected. - Neal -----Original Message----- From: Robert Jordan [mailto:[email protected]] Sent: Friday, December 17, 2010 6:25 AM To: [email protected] Subject: Re: Cannot Escape Special charectors Search with Lucene.Net 2.0 On 17.12.2010 12:29, abhilash ramachandran wrote: > q = new global::Lucene.Net.QueryParsers.QueryParser("content", new > StandardAnalyzer()).Parse(query); I believe the issue has nothing to do with your query syntax. StandardAnalyzer is skipping chars like "&" during the indexing process, so you can't search for them. Robert
