[Feature] Ability to search inside specific tribes

I was about to search for posts related to filtering on /t/ideasforsnapzu when I noticed there isn´t an obvious way to search inside specific tribes. This will only lead to a possible accumulation of repeated recent posts.

Another problem I noticed was the search. Searching for the words "ideasforsnapzu" and "filter" led to completely unrelated results. Not even the tribe appeared on the results.
