For a while the ability to refine a search based upon TVR model seemed to work; now it appears that despite selecting Chimaera only, hits are retuned from all the other forums.
Can anyone remember the string for searching at forum level with Google?
Update: It seems to be a Safari issue, I have just tried Chrome and it only returns hits from the Chimaera forum. Safari whilst having "Chimaera only" selected returns hits from all the forums. Strange!
