Search Design Pattern

Vote count:

I'm doing a design for a search functionality. I identified that there is a generic "Search" use-case and SerachItem1 and SearchItem2 specialized use cases. Both the searched are done by invoking the same web service from back-end. To design this search functionality in an enterprise application, I'm looking for good patterns. I thought of command pattern where I encapsulate different search criteria into commands. Is that a good idea? Are there any better patterns which I can follow? Appreciate if you could give me some references.
