These are both of the problems I regularly have. The first one I immediately saw when reading the title of this submissionw as the "super case insensitive" that I often see when working on Go Codebases particularly when using a combination of Go Classes and YAML or JSON. Also happens with command line arguments being converted to variables.

But the string split thing you mentioned happens a lot when searching for OpenStack error messages in Python that is often split across lines like you showed. My current solution is to randomly shift what I'm searching for, or try pick the most unique line.
