The LIKE operator is used to match with a specified value in a field. You can use it to find items or issues that contain, start with, or end with the specified value.

The NOT LIKE operator is used to exclude items or issues that match a specified value. It returns results where the field value does not match the specified value.

For example, find the Summary that contains test%.

summary LIKE 'test%'

summary NOT LIKE '%test'
