Hello,
I would be happy to help. 
From the image you shared, it appears that you’re searching for ‘7133’, yeah?
I can’t say I’m familiar with that being a reliable search strategy, to the best of my knowledge. In most cases, UWorld QID’s are coordinated via tags in the Anking Step deck, which requires a bit of translating the QID’s into workable search strings
For this reason, it’s not all that convenient to do it manually and pretty much everyone I know uses an add-on to convert the QID’s into a searchable string (which also has the benefit of being able to search for many questions at once, being a lot easier). The most popular add-on that does this can be found over at https://www.theanking.com/, if it’s helpful
That’s the only way that I’m familiar with which to reliably search for UWorld QID’s via the browser, at least
Please let me know if that answers your question, and if there’s anything else I can help with.
