Improve Gdocs index page searching

[ikesau]

Now that we have 200+ Gdoc articles, we should improve the index page view a little.

Check with the authors if they'd prefer substring matching to fuzzy matching, and add some more facet options (published/unpublished, author, topic)

@ikesau this was starting to annoy me too much so I did a small version in:

• Better search on GDocs index page #2779

Ike, from your perspective is the new change good enough for now?

[ikesau]

I'd like to add a facet for published status still 🙂

Closing this one for now, but of course feel free to improve the search space here without needing an issue for it.
