Gotta say, #hashtag search on #GtS is a lil' b0rken, fam.
Totally unable to search for the #Android hashtag, but rather it gives me every hashtag that starts with "android," but not "android" itself.
The same thing happens if I search for "androi"
On Mastodon, "android" is the first result.
If it helps to eliminate possible client foibles, here's the result when I use toot instead of Tusky:
