I want an "Advanced" search function

Recently I have been posting more on the boards again, while doing so I have found it aggravatingly annoying to try to find ANYTHING that I had posted on the old boards seeing that the Forum Archives doesn't have a search function, so I suggest that you implement a Advanced Search feature that lets you not only search for things like particular users or even to see if certain keywords have been mentioned, but also lets you choose if you want your search to include archived posts or not.
