I must agree that the new search utility is less useful. Under Advanced Search, when specifying a username I could ask for all posts by that user or only threads started by that user... now, I can no longer do that. That functionality was very useful and it is a serious drawback to have it go missing.

The time-stamp search should include "weeks" instead of just days, months, and years. Sure, it's easy to say "14 days" but people don't often think like that.

I liked the old search functionality better.
