Smart use of Gmail Filter and Label

I just figured out the solution of my old problem. I am a member of many mailing lists and I use to get many mail. During conversation , mails which are having "@narendra or hi narendra" are difficult to trace out. Today I just made a new filter in gmail so that any reference to me will be labeled as "Narendra" and I choose Red color for it. Now I can easily traceout those mails.
