----------------------------------------
The PR is done on the 8x branch. Is it the good one or would you prefer on the
master ?
[~joel.bernstein], I think your are the master of collapsing/expand features. :)
Would you like to take a look at this please ?
Thank you !

> Currently the expand component is creating queries (bit sets) from the
> current page document ids.
> These queries are sadly put in the filter cache.
> This behavior floods the filter cache and it becomes inefficient.
> Therefore, the group query should be wrapped in a query with its cache flag
> disabled.
> This is a tiny little thing to do. The PR will follow very soon.
