What I usually do is open a second browser window (tab) with the artist displayed. Going to the Works tab shows me an alphabetical list of the works associated with the artist. If I find the work I’m looking for, I copy the link address and paste it in the search box on the editing window (tab). If I don’t find the work on the artist page, then I know I need to add a new one.
Edit: I sometimes use the same process when looking up recordings, if it’s a common title with a long list of unrelated entries.
