I have a people search page for our staffdirectory. I want to filter out some user profiles that are for generic accounts. I have the following in the 'Append Text To Query' box in the webpart.
contentclass:spspeople; -preferredname:"TCM\Window*" -preferredname:"TCM\CoatCk" -preferredname:"TCM\coreuser"
The problem is the system seems to ignore everything after the second restriction on preferredname. If I move things around whatever is listed in the first two restrictions always works, but anything after is ignored. Is there a limit of two restrictions on one of these properties?
