Marco, would you mind reviewing this? I don't know your GitHub handle (or if I did I don't remember it), but the PR is here: https://github.com/0c0w3/urlbar-search-interventions-experiment/pull/1

There's documentation in QueryScorer.js that hopefully explains things clearly enough, and there's also a test. I explored more complicated ways of categorizing query strings, but in the end the simple method I landed on seems to work well enough and better in some cases. I asked Verdi to try it out but haven't heard back yet.

Ah, mak77, of course :-) I'll leave the needinfo just in case you miss the GitHub request.

done, I also forwarded gh notifications to my moz email, so they should be more visible.

Thanks, I merged the PR, so this bug has been fixed. I expect we'll want to make tweaks to the scorer as we continue with development, and we can file new bugs for that.
