Search Strings: Show all posts within a specified period

[mhuckaby]

If I want to search my forums from a URL, what is the string I should use to show ALL posts made within the last 30 days (not just new posts, for example)?

I've read this post:
http://www.vbulletin.com/forum/showthread.php?t=107955

... and I understand the variable options, but what options are there other than "getnew," "getdaily," etc. as the process to be used in the string?

For example, if I typed a string similar to this, but obviously inserted my forum address in place of "www.yoursite.com/forum":

http://www.yoursite.com/forum/search...&searchdate=30

...what do I type in place of "process?" to show all messages, not just new as in "getnew"?

Thanks,
Mark
