>>I tried verifying what you saw with both GW 6.5.4 and with later versions. I agree with you. I know that >>there are similar defects already submitted to engineering with regard to searches using the Email Address >>and Name properties, but since we can verify it was working in GW 6.5.4 that may up the priority to get this >>issue fixed in current versions. I also note it isn’t working in GW 7 SP1. I therefore created Defect >>#205166 and submitted it to CPR this morning. Hopefully they can get this issue taken care of soon.
>>Thanks for bringing up this issue
