> 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.
