To provide some context:

I have seen others mention this before. The quick search bar was changed in 3.1.2 in the following PR #8073

The old quick search searched in only the loaded page, but it searched in all fields, with partial matches and regex support. The new way uses the q filter of the object that is being searched to look up all possible matches in the database. In most cases this searches a few fields with no support for partial matches (not sure if this is the case for all objects).

Obviously the old way was broken from a usability standpoint (only searching in the loaded page), sometimes making users increase their pagination setting, causing slow page loads. I could support a feature request for making the quick search better, but it would probably be blocked by the following feature request: #7016
