Lookup work items by field in portal

[Sawyer_ Rodney]

I got a new requirement for a customer service team that is moving to JSM... They are just entering tickets through the portal and so normally would only need JSM Customer permissions, however their process is that when they are entering a ticket, they lookup that customer they are working with to see what other issues they have had in the past.  The customer service person does not need to transition, edit, or even comment on the previous tickets, just know that they exist.  

So is there a way to have them be able to search old tickets through the portal without giving them Agent or Jira Software licenses?

Hello @Sawyer_ Rodney 

With only native functionality that user would have to be the reporter of the other issues, a request participant on the other issues, or a member of the Organization(s) with which the other issues have been shared to be able to see them through the Customer Portal.

There might be a third party app that could help you. Have you looked in the Atlassian Marketplace?
