Adrien Grand commented on LUCENE-7680:
--------------------------------------
For the record, this would still allow compound filters that wrap term filters
to be cached (eg. a BooleanQuery or a ToParentBlockJoinQuery).
> Never cache term filters

> Currently we just require term filters to be used a lot in order to cache
> them. Maybe instead we should look into never caching them. This should not
> hurt performance since term filters are plenty fast, and would make other
> filters more likely to be cached since we would not "pollute" the history
> with filters that are not worth caching.
