Search in GitLab

Does anyone know how to search better in GitLab. Currently I'm using the standard GitLab search. I'm searching for "<<loop>>" where I intend the quotes meaning exactly that string as usual in a search term. But I get lots of results mentioning loop, without the angle brackets. Moreover I want to sort the results by date or ticket number, and I can't see how to do that. Does Google index our repo? Can I use Google to search it somehow? Thanks Simon
