Using Sphinx's searchtools.js leads to more HTMP calls because it grabs the context for each search result.

The custom searchtools.js on main adjust the behavior by not loading the summary when searching.

With d4f7363 (#24128), the search summary is disabled, which is consistent with the behavior with the search behavior in the 1.0 docs.

We can cherry-pick this PR into the 1.1.X branch and that should update the docs for https://scikit-learn.org/stable/ without needing to release a new version.

Trying the search in the CircleCI artifact e.g. https://output.circle-artifacts.com/output/job/41a9e69d-f629-4a96-9d64-ccd07f94afaf/artifacts/0/doc/search.html?q=neighbors there seems to be some weird matches that contains some inline HTML e.g.:

If that's more than 15 minutes to fix, I am fine with merging as is, as this is a lot better than a completely broken search.

The incorrect render was a Sphinx bug. I ran the following to update just the doc dependencies:

python build_tools/update_environments_and_lock_files.py --select-build doc

The search page now renders correctly.

Thanks a lot, let's merge this one!

The search now works for the stable version:
