“The search request was unable to connect to the Search Service.”Installed Fast search server binaries on a 64 bit machine and connected it to Sharepoint 2010 installation.
Everything went smooth, was able to create Query Service application and content service application, FAST Content application was able to crawl my data but still when i fired a search from FAST search center site ,I got an error message
“The search request was unable to connect to the Search Service.”
After hours of headbanging which included restarting the machine and recreating service application ,I looked at the obvious culprit
The QRproxy service on my fast search server was Dead.
To know about status go to your Fast Command shell and type
Every attempt to start the service failed
nctrl start qrproxy
Finally found out the error in system event Log it did not have Windows identity foundation installed.(Windows6.0-KB974405-x64.msu)
Install and try starting the QRproxy service and it should be all set
