Spiders and Forum Searching

[pforp]

hello, i was hoping someone could help clear something up for me.

do spiders use the forum's search option to crawl pages or do they just crawl threads that they have access to? i understand that spiders have the same permissions as the guests do, but i wanted to make sure that i was not affecting the spider's ability to crawl if i decided to disable the search option.

thanks in advance.
