When you say the rule summary fields, I assume you are talking about the "Additional Rule Info", "Ticket Number" and "Ticket Requester" fields in a rule. I just tried a policy search for something contained in these three fields in the R80.10 EA SmartConsole and it worked, so looks like the solution is to upgrade to R80.10.
Although searching has been improved somewhat, it appears one still cannot search for a NAT Address in objects or the policy in the R80.10 EA SmartConsole. Workaround remains to bring up the legacy SmartDashboard and run the NAT address search from the Objects List tab along the bottom of the SmartDashboard.
