Homepage search box bugs

[hwood-vivup]

The homepage search box at the very top of https://www.openclimate.network/ has these three bugs (I can split these up if preferred):

• If I type something and hit Enter it says "Thank you! Your submission has been received!" (not what I expect when searching. I wasn't entering a "submission"! Is there a database slowly filling with search nonsense from people like me?!)

• If I type something and hit "Explore" green button on the right, nothing happens. No error in the js console.

• (Minor) If I start typing more than three letters then it begins showing search-as-you-type matches below the box, but the first search I tried was "UK" (Awkward I know, but maybe some super-short matches could be pre-programmed)
