I don't know whether this is relevant, but you might look at KinoSearch -- at least for ideas. Basically, you need some sort of process that will read through your set of documents and build an index to identify all the locations of all possible keywords. Then you need a separate query process that knows how to read the index data, and how to use the information provided there to locate the specific documents that meet specific conditions on particular keywords.

A database solution would probably work okay, but people have built "search engine" apps that are better optimized for this kind of task. KinoSearch (which I personally have not used) is one such engine, built with Perl and C.
