Here's another cool feature for the WMF developers to ignore.

Icons.

Look at these ajax search results for "ana":

Don't worry about the compression of the screenshot, it's nothing compared to the thumbnails. Anal sex shouldn't have a thumbnail (I blurred it for the screenshot). The thumbnail for anaphylaxis is okay. The thumbnail for Ana de Armas isn't great, but passable I guess. The thumbnails for analog-to-digital converter and analgesic are not terribly useful without a caption to provide context.

That's 1 good, 1 passable and 2 somewhere between neutral and passable.

That just leaves the thumbnails for analytic philosophy, anatomy, Anaheim, anabolic steroid, anatomical terms of location and Anatolia. 6 thumbnails that, in my eyes, don't rise above the "garbage" level.

If you want something visual (which is admittedly easier to take in than a wall of text), try using the category system and/or Wikidata (specifically "instance of") to pick a category icon that can be optimized for display in search results. Here's a mockup, it's ugly because I just scraped some random icons from Commons together:
