Check out this thread for the latest details on any changes to this search site.
The search database only goes as far back as Jan 1st 2009 for the industry forum sections, and only as far back as April 15th 2009 for others. Search results can be up to 15mins out of date.
If you register and login you'll be able to save searches and subscribe to them, getting email alerts whenever new posts match. For example you can use this to be notified whenever someone replies to you in the forums.
Enter something into at least one of the first three boxes. Using more than one box makes your search more and more restrictive (all must match).
If you only enter something into the title box (or tick the 'only threads started' box and do a MM# search), you will do a thread search where the results will be a list of thread title links. Otherwise results will be all matching posts.
