The last thing I'd do is partition my index into two, unless and until I really *knew* I had speed problems. The added complexity isn't worth it and your index isn't huge, so search speed can probably be addressed without that complexity.
Filter queries are probably your first choice here. Memory isn't an issue because they're implemented (as I understand) as a bit vector. That is, each one (and you only have two) will be 250K plus a slight overhead. Utterly insignificant. You can easily experiment with the differences in speed with a single index between q and fq if you use a single index. You're right that if you just tack on an AND to the q clause, the true/false will contribute to the score, but I think they'll all contribute the same amount, effectively doing nothing to the ranking. There is something of an efficiency argument here, but maybe not enough to notice. Faceting is generally used more for answering questions like "given I've searched on query <Q> how many of my answers are in groups A, B and C". Than drilling down to things like "show me the ones in group C". Which, while related to your problem isn't what it sounds like you're after. When measuring speed, remember that the first few queries aren't representative.
