We are using 2.13. The keyword search feature for the OPL in the Library Browser appears to be not working. I just ran OPL-update and restarted apache to be sure.
If I go to advanced search and type in a keyword (concavity), I'm not sure what is supposed to happen. It doesn't auto-refresh like when you use the drop-down taxonomy menus. If I press ENTER it reacts as if I had clicked "Add All". If I directly click "View Problems", it says "There are no matching WeBWorK problems". But there are many, for instance Library/Union/setDervConcavity/4-3-49.pg.
Does anyone else experience this in their Library Browser?
