The short answer of things is our database is just to big. With everyone using the search feature of the site I am glad as this cuts down on countless repetitive posts, we had to implement a new search engine similar to what google uses for their search algorithm. This is done in a separate "database" and is re-indexed on a scheduled basis, if you are looking for really recent posts they will not show up until the next re-index.I remember when I first joined this site, it used to bring up todays posts. Wonder what changed?
