Hello, I am curious about total-numbers for lists and search.
Is it possible to achieve and display total numbers before doing a search and filter operation? Or even update those numbers after a filter is applied?

e.g. this forum:
It displays the number of replies for each topic. How was it achieved?

e.g. products/marketplace:
There is only 1 total number for the whole section. The actual filters or "categories" do not show any number. Which is bad UX, because the user has to guess where are any articles contained... Can search selects have a total(#) as well? Before doing a search and filter operation.

Thanks in advance.
