wouldn't it be better for this user who is not able o find those notes, that you explain him your approach, how you search to find this note himself? this could help him for his lifetime.
Just giving him links, will only make you to his searching slave.
Of course it is possible to put an answer with a link to an OSS note, but any link should have some context.
....and it should not be an answer to a basic of frequently asked question.
