Hi Praveen, I know this is not your original question, but if you have a product search system, you should really look into adding auto-completion of queries to it. Concretely, you probably want to start with auto-suggesting product names. People like this, know how to use it, and it allows *them* to choose precisely what they want. To use your example, if they typed "Sony L" and auto-complete shows them Sony LED ... and Sony LCD... which one will they choose? Well, they know what they are looking for, so they'll know exactly what to pick. See URLs below my name for some auto-complete examples.
