I log in ONAP portal and bring up AAI UI app. In the app search box, if I enter "customer called Demonstration", I can see all service-instances under user Demonstration. However, if choose a valid service-instance-id and enter it in the search box as "service-instance called service-instance-id-value", I get an error message saying "invalid search terms". 

Tested on Amsterdam release, please see the attached screenshots.

In Amsterdam Maintenance release, I failed to search with query "customer called Demonstration" on AAI UI, even though I can see the customer with POSTMAN.
