Oracle's Metalink is a very - veryyy useful tool when it comes to errors and warnings and unanswered question. Oracle got a huge and helpful documentation.
But.. if you are searching for a patch or patchset you're in trouble.

this afternoon i was trying to download a patch to upgrade my rdbms 9.2.0.1 to 9.2.0.8 ... and i searched for a patchset for 9.2.0.1 . There came swarm of results. But couldnt find anything about my upgrade issue!! Then i gave a try to search with 9.2.0.8 . Aaaaanddd it was there! at last..

Isnt it silly to make the patchset search based on the new number? i am trying to upgrade the old number dummy!( maybe this is only weird for me because im not a oracle guru, i'm just an inexperienced dba)
