i go to advanced search every time and it works marvelously. can always find things quickly each time. it helps that the advanced search function has a time frame you can poke in..... and other parameters not available when you just use the quick search off the tab at the top.
its all in an SQL database. so the search is fast and efficient with parameters. the quick search off the tab at the top searches like over ten years worth of posts automatically. that is supposed to be settable in the future, but right now its the same setting as what the software uses for the limit of depth to the search function period.
