But filters are in-memory biests so have to be recomputed every-

- store the filter (that shouldn't be very expensive but I never
tried)
- modify the index to add a flag ?
Say, for now, my filter contains 70% of the documents.
Could you frame your questions around a use case?
A filter is really designed for long-term use, not for instantiation
for every search.

Hi all,
I have to filter my searching in two ways:
1) by score, I want that only docs with score higher than a
threshold
are returned.
2) by num of docs, I want that only, for example, the first 20 docs
are returned.
It's better do it with a queryfilter or search for all and after
look
through the hits with some conditions?
A QueryFilter can do neither of these criteria. I recommend simply
doing a search and limiting the Hits shown based on the desired
criteria.
