It seems to resolve into
`solo,oc name needed,oc*` cuz I get results where `oc` and/or `oc only` exists, regardless of whether `oc:...` actually exists, like \[SFW\]>>2927426t where `oc:...` doesn't.
Same with [`solo,oc:*,oc name needed`](/search?q=solo%2Coc%3A%2A%2Coc+name+needed) where I merely swapped the positions for completeness, seems to resolve into
`solo,oc*,oc name needed` cuz the results are identical.
(I searched this thread with `topic_id:8658,oc:` and `topic_id:8658,*oc:*` before posting.)
