Are you adding the same 500 terms to each query? Or even a similar set? If so, then filters could help. If the 500 terms are different for each query, then filters probably won't help you.
How long will the filtered doc id be retained in the memory? can I manually manpulate this filtered doc ids, say pre-populate a sets of filtered data in memory and play with memory sizes.
A filter requires 1 bit per document in the index. So, if you have 1M documents (which is what I recall you have) then each filter will require around 125kB. You could pre-populate them. Check out QueryFilter.
