keyword1).filter("keywords =", keyword2).filter(...) ?

I agree, I'm definitely not happy with the multiple indices. Not to

happens soon. It looks l

union in my application code.
If I thought the OR was going to return a huge number of results (too
large to practically process in a single request) I would start a task-
queue task to fetch the data and then have my front-end
