Hi friends I want a code for search engine for example when I search a data in text box like "name of employee whose salary is greater than 20000" it should give me data which contain name of emp whose sal is greater than 20000.Is there any ready made code or tool who separate important keywords & search data by using that keywords in database. I want it in c# or asp.net
