I have a document library with a custom column named "compound" which is just text.

I want to put a filter (input text box) on that document library page so the view shows only the items where the compound column contains my typed-in text. Optimally, wildcards such as \* or ? or full regular expressions could be supported... but for now, I just need a "contains".

The out-of-the-box text filter seems to only support an exact match.

The result output would be identical to what I would see if I created a new view, and added a filter with a "contains" clause.

Third party solutions are acceptable.
