I think rg isn’t ignoring sourcemaps to be fast. It tries to ignore based on .gitignore and similar files, but maybe the sorcemaps are ignored for being binary.
I thought so too. The documentation for all state they honor .gitignore. In my case, the compiled code is committed.
My query was for a generic term "src" - so that likely trapped the file-path embedded within the long lines of a source-map. Hence the massive file-size difference.
The main goal of respecting gitignore is generally to decrease noise in search results. But, this does of course also have the effect of improving performance in a lot of cases.
