i posted replays on there like 2 years ago, is there a way to seach for them?

Do you remember the [tags] you gave them? like "decap, awesome, lol, etc..."?
If so just type in the tag. But if you can't idk what else you could do.

Nope I don't remember

Then no I don't think there is any way to find them... unlesss you go through all of the pages 1 by 1 O_O

There is no way to search the replay if you forgot the tags. Have a unique replay tag and save it in notepad. In case you need it later.
