Fix hybrid search after a bad merge

Created by: camdencheek

I merged a passing PR after another PR was merged and the other PR depended on removed things. This should fix main.

Test plan

This is all behind a feature flag and the build is currently broken, so I'm just going to merge when it passes. cc @keegancsmith I think I fixed this correctly (I copied this code from some other zoekt type translation), but I have not tested hybrid search with the change.
