I had a hard time coming up with a comprehensive list of Search Engine Referrers for vBulletin. There was almost no information available on the web about what to put in the Search Engine Referrers field other than the typical .google., .bing., and .ask.. Granted, some of these may not work, but others definitely work, and it's easy to tell based on what crawlers are accessing your website.
The first step would be to navigation to your "Search Engine Referrers" section of your vBulletin options, which is under "Stye & Language Settings". It might be notated as a similar function in your other respective forum of content management system software.
The following is the list that I use. Again, not all of them may work or query as much as you would like to, but a majority of them do, especially baidu and yandex.
