The search function on Tumblr is becoming more ruined. Searches by “recent” are starting to omit posts that aren’t being omitted in “Top”. It’s getting harder to find posts in “Recent” that I know for a fact are in there. I’ve objectively confirmed that at times Top will have two posts when Recent has only one of the two I just saw, usually when I search a more specific term than is common. And other larger-scale variations of those numbers.
Tumblr is to some non-zero degree using an arbitrary decisions algorithm to choose what we see.
