I just wanted to clarify that the last_activity_date filter has been added (this was in January, sorry for not updating you before).
The other part of this request is exceptionally complicated (Matt was extremely optimistic in his previous reply 
).
Weâll keep this thread open for the introduction of âdependent filtersâ in BrewwQL. Currently, all BrewwQL filters are evaluated independently and so sometimes you cannot get to the result youâre looking for (see Breww QL & 'within range' query). It would be great to find a solution for this.
If youâd like to see âdependent filtersâ in BrewwQL, please give this thread a vote
