How is Google "not an option" : without search, how are you doing any better? Unless the same question you asked is on the first couple of pages in a forum, your question may be buried under several pages and your answer not even found.
Google is currently better than what we have now (which is no function)
Again, if the search function was offered, there would be no way for the forum to function properly. with over 10000's post a day, each SEARCH request is saved to the forum's DB (I've run several Vbulletin based websites). The server load would be insane.
and they'd probably limit your results to the first 200 results (from the most recent). So looking for older answers, would require you to use other means to find it (Like using Google). So if 1000 people posted about "Kaliyo" you'd only get the most recent 200 results.
And as long as your name is displayed here and indexed by Google, you can find your threads and those you participate in in Google:

google is far better than any forum software search function. On bigger and busier forums that I visit, I've had to search forums for posts dating back several years. Care to do that with a forum that gets nearly 15K posts over 1000 newly created threads a day?
