I see a lot of WTS and don't want to see any WTS

Describe the solution you'd like

ability to search by plain text. tried to enter "not WTS" into the PGF search box but it tries interprets WTS as a keyword rather than performing a plain text search

Not possible, see FAQ on how to deal with WTS groups: https://github.com/0xbs/premade-groups-filter/wiki/FAQ#how-can-i-filter-groups-by-name-eg-search-for-key-levels-or-exclude-wts

Oops, Sorry! I did open the FAQ and even searched for "text" to find the answer to my question but didn't think to search for "WTS" specifically -- thanks for the response and sorry again.

To save yourself from morons like me, you could add a note in the "Advanced Filter Expressions" tip in the UI itself that explains the search keywords: "Plain text searches (such as WTS) are disallowed by the API"
