Basically, I have a bunch of entries in a database. Call em movies. Each is 
tagged with a collection of arbitrary tags: release date, studio, genre, 
etc. There's no specific collection of tags, but each tag is either present 
or absent, with no other associated value.

Now I want to represent groups of movies. I want to be able to say, for 
example, movies that are from Warner Brothers, and that have arabic *or* 
french subtitles, but aren't rated R, that are out on DVD or out on VHS, ...

So, basically, I want to be able to express a fairly general boolean 
equation on an arbitrary collection of variables and store it as a SQL table.

However, I haven't been able to figure out the google terms that might 
actually give me something other than a tutorial for using the boolean type 
in SQL.
