Once you have populated your knowledge base articles, you can setup your support portal to "auto-suggest" solutions that are in line with a customers' query(Ticket Subject) when they are submitting a ticket.
If you navigate to Admin > Channels > Portal --> Settings tab, you would see an option called " Auto-suggest solutions while creating a new ticket", available under *"User Permissions for portal" -->Who can submit a new ticket on portal.*
You could turn this option on and each time when the customer starts submitting a ticket, based on the text added to the Subject, corresponding Solution Articles would be auto-suggested.
