Hash table with more than one key?

I'm trying to make something like a hash table that can locate a value quickly given a key to match. But my problem is that the data can't just match one key to retrieve a unique value, it must match three different keys to get the correct value. Is there any sort of existing data structure that provides this sort of lookup capability?

I know a hash table is not what I want. I just want to know if there's anything that offers what I need, a table that matches multiple keys to find a value quickly, so I don't have to program this from scratch.
