Just to clarify, this doesn't have to be fast. I'm just looking for a 
structured representation. I'm happy to do multiple searches and such, since 
the result will be cached and only regenerated for the collections that 
change or when movies are added or whatever.

I'm just trying to avoid storing the selection criterion as a big TEXT blob 
that looks like an equation.

I'm thinking like a table of "has all of", a table of "has some of" and a 
table of "has none of", for example, except I'm not sure that's flexible enough.
