Your original formation of the filter query has two problems:
1> you included a “+” in the value. My guess is that you misinterpreted the
URL you got back from the browser in the admin UI where a “+” is a
URL-encoded space. You’ll also see a bunch of %XX in the URL which are
other encodings.
2> you include double quotes, which can change things to be phrase queries.
Looking at the debug version would have helped you pinpoint these.
