I’m having this problem as well. It’s pretty random which words work to get results to show. If I search for a single letter from a job title I’ll get results, but if I add another letter no results will show. I’ve tried the code above — which didn’t have any effect for me — and also reverting to the earlier versions of the plugin as suggested above. Reverting to an earlier version makes no results show at all (before the search), so that’s a show stopper. Any other suggestions for things to try?
