Understandable there might not be much more to do here given the apis aren't returning the results either. No worries then.
As an update: boosting doesn't seem necessary if the search contains "language" (similar to go lang vs go I imagine). The article itself doesn't show up in normal or programming lens search, however the reddit article is now at the fold rather than far below it.
Anyway all good, thanks for looking into it (and sorry for only checking back 23 days later)
