Some people call this "faceted search".  We discussed it at...

Probably, you'd want to do rapid prototyping in Perl, then port to C/XS.

The hitch is there isn't a formal C API yet.  The fundamentals of the  
OO design are done and ought to work great, but we need the surface  
level stuff.

Whatever we come up with for the C API will be clunky and weird, but  
we're just going to have to accept that.  We aren't doing serious  
language design, and if we pretend that we are, we'll never finish.

Absolutely, it's possible.  It doesn't belong in core KS, but it's an  
ideal extension, and I look forward to supporting whoever takes on the  
task of writing it.
