Interestingly, if I search for words in Groupoid's post that Wave did NOT repeat (eg itsy-bitsy), Groupoid's post still comes up; however searches for the repeated words (eg. blinky) only show Wave's. The search order also seems completely out of wack - if I search a moderately common word such as "Lalli" the first result is from 2022, the next result from 2023 and the fourth result from 2017.
This seems like a fairly major issue with the search function in general, and one I am definitely not confident in my own abilities to solve. If people are finding this an issue I'm happy to contact Hushpiper and see if they can do anything.
