Making Advanced Search

Question

Dear Sir/Mam,

I am making an advanced search page from which a user can select a certain options and also one keyword textbox is there. I want that the Keyword text field should work in such a way that it should break up in literals and ignore the spaces, commas and dots. If the keyword is in double or single quotes then it should understand it as single word for search. I am using C# and SQL Server.
Can anyone help me in keyword field. How can I ignore the blank spaces and other characters from the textfield and also Character case.

Thanks & Regards,
