Hi I tried that approach, I did used escaping using the "\", and the query has the special charecter, but i got no results that time.
What I found out was when I use Standard Analyzer on "ABC+S", the terms generated are "ABC" and "S" and '+' is getting lost. When I used whitespaceAnalyzer or keywordAnalyzer (or use standardanalyzer but don't analyze this field), it is working, but it is case sensitive. Can anybody suggest me how to use Whitespaceanalyzer/keywordanalyzer along with lowecase filter or how to make Standardanalyzer not to generate tokens based on these special chrecters.
