I am currently removing all things related to the old search from the MainActivity and MainFragment. During this I saw the retainSearchTask boolean which changes the behavior of MainFragment#goBack to go back to the search (which doesn't seem to work as far as I can tell).

I think that it is helpful to be able get back to the search in general, but I don't know if changing the behavior of goBack is ideal. I think adding an extra button "Go back to search" might be more intuitive.

Since the current implementation does not work with the new deep search in the SearchView, I will delete it. I think that this should be handled in a separate PR.
What are your thoughts about this?

This is ready for review! I know that it looks like a lot of changes, but most of it is actually just removing an if statement and reducing the indents for the whole block. Since git stores the diff line-based, every line where the indents are reduced are marked as a change...

Great work! Is it possible to include regex search in filter search and index search? Currently it only works when user does deep search. It leaves user confused. We either need to mention this in settings that regex will only work in deep search or find a way to include regex search in filter and index search.

I implemented this in #4050 so that this PR won't become even bigger. If you want, I can completely disable regex search here and it would be readded when #4050 is merged.

Sorry that was an oversight on my end. Amazing work here! This should be good to go :)
