I have two Sharepoint 2010 farms called FarmA and FarmB. Both farms have web applications and content. FarmA is also a publisher of the Search Service Application. It has been configured to crawl content in both FarmA and FarmB.
I have successfully published the Search Service and the consuming FarmB see results from both farms when I do a search from a Enterprise Search Center site collection. The issue that I'm having is that when I do the same search in FarmA, I only see results from FarmA. I'm not sure if the results are getting security trimmed. I am using different farm accounts for each farm, though I am accessing both web applications with my account. Or is there some additional configuration required on FarmA to show results from FarmB?
