Hi @Dave, interesting question. I haven’t had any issues with search on Discourse myself, but admittedly I don’t use it much.
I’m not sure how common the term ‘R4R’ is on the forum - I don’t remember it actually being used. Using Google to search the forum only produces a couple of results too, although Google only has access to the public categories.
Searching for Ten does bring up some random discussions for me, primarily in Spanish:
I wonder whether that’s because the letters ‘ten’ appear in a lot of Spanish words, e.g. the verb ‘tener’. These are the instances of ‘ten’ in the top ranking discussion from that search:
tener, existente, tengan, Tenemos, contentas, entender, Ten en cuenta…
This does seem a bit unsophisticated as search algorithms go. That said, @Ten’s profile does come up for me (at the bottom of the screenshot above). Does that not happen for you @Dave?
The Discourse crew do seem to be working on some tweaks to search, judging by the latest beta, but I think these are primarily visual changes.
