How do I do an advanced search only inside a single category.
In other words, I want to search for some text "Why did the chicken" only in '''category:clean-jokes'''.
I want only results of pages that have that category.
Another example: I'm searching for "immune" only in both of the following categories: biotechnology, scientists-from-timbuktoo
I want only results of pages that are in both categories.
A third example would be to search for a term inside pages listed with any of those two categories.
