Recently Firefish changed their search to only index public posts. Currently Akkoma indexes both public and unlisted posts.
I feel that people generally choose the “unlisted” visibility to reduce exposure of one’s posts to random people. Having those posts show up in the instance search results I feel defeats that purpose.
I think Akkoma should follow in Firefish’s steps by also only indexing public posts.
Maybe instance local unlisted posts should be still included? I think search can be useful to find some community internal discussions that might be unlisted to not pollute the public timeline.
