How quick search sub-category in category?

Example: i wanna search “Bình Thạnh” sub-category of “Nhà đất cho thuê” category



(Note the initial hash # and the colon : between parent and child categories)

You can see this yourself if you use the advanced search, go to categorized and select a subcategory.

You should see that discourse fills in the search area with the correct syntax - in this example the announcements subcategory of the parent category features gets translated as #feature:announcements.
