I have a SharePoint with Fast Servers. I have multiple content sources in my Fast content SSA but right now I have one crawl component. I would like to add one more crawl components. I saw this Microsoft document but I am not sure do I need to Full Crawl after this? If yes, can you please tell me why is that as all the indexes are in Fast search and crawler always keep temporary index files so If I add another crawler now in content SSA , why it affects it?
I am not sure if I want to add another database but as of now I just want to add one more crawl component on different server. http://technet.microsoft.com/en-us/library/ff599534.aspx
