Do you think it works okay, at least so far as local/federated communities go? What are some adjustments you might like to see to it?
Personally, I still find the dropdown/search combination somewhat unintuitive and at times it can feel clunky, although it has definitely improved. I sort of think a regular search bar to filter through communities/posters might be better, with a separate dropdown beneath or next to the bar, so one knows one can directly search by community/username, but I can see why it was done the way it was to a degree.
It has worked okay for me. I haven’t tested this out in detail, but like strings didn’t seem to work like how I expect. There seemed to be a lot of unrelated results where the string is taken as a Boolean OR set of arguments. Like searching for “AI (term)” mostly generates results for words that contain “ai” like “contains, again, etc.” That can make contextual detailed searches impractical or force more creative single word searches and poor overall results utility.
