opi does not return as same results as OBS. Please see the screenshot:

Maybe currently it doesn't query from title or description.

Looking at the OBS API docs, I don't see a way to query for description: https://openbuildservice.org/help/manuals/obs-user-guide/cha.obs.binary_tracking.html#id-1.5.10.12.6

Also this is referring to a package regarding OBS logic, but an OBS package can still produce multiple RPMs, so it makes sense querying by rpm name as we already do.
