Forum search just doesn't work

I have noticed this for a few years now, so wondering if it will ever be addressed, but the forum search is fairly broken.

• Selecting 'filter by forum' seems to return no or little results. For example, Select Comics and search for Bless. 1 Result, with no mention of any "Aqua Bless" results.
  

• Search text is cleared every damn time a search is performed, so modifying search is incredibly frustrating. Example, any search
  

• Selecting a 'sort by' causes all other form elements to reset to blank. This element seems to be for after a search is done, to order existing results, yet it is above the 'search' button, which makes no sense. Example, enter 'Oni Bride' and selected Order by Date, form resets. Enter 'Oni Bride' and search, then select Order by Date, results order, but some form elements are reset, such as Filter by Forum.
  

• Filter results by user, doesn't work at all, always returns no results. Example, enter 'Brittany' in Filter by User and search, no results returned.
  

• Zero feedback provided after searches, such as 'no results' or even 'search term required'
  

• It also seems that some of the search results depends on if the user who posted is registered or subscribed.
