Guide - How To Search 2.0

With respect, all the options are available, with the exception of minimum number of replies and order by most replies.

That is not "many"

The only option that is partially available is specify a sub-forum to search outside of the forum you are currently in. As it is a quick search, it does not need to offer all those options, particularly if you're just going to use

You say what options you use, which amounts to the same thing. Especially the "I've never had cause to use this, just leaving it on default, but it could be useful if.." sentence.

we only have tools to limit the results further than the already current limits.

You said nothing about how including a word containing 3 letters or less fails the search entirely and gives an error message, nor about how you can never have results beyond a certain date nor more than 200 results at once.
Honestly this post should have shown how to search the forum using google instead.
