How do I use JQL Advanced Search to find two parts in one comment?

[Jen DeAngelo]

I'm using JQL Advanced search in JIRA Cloud, and I want to search for tickets that contain MKT + (anything else following). I've read the documentation on Advanced-searching-keywords-reference-764478340.html, but it doesn't have an example. 

I've tried: 

Project = XYZ AND comment ~MKT OR Description = MKT

Project = XYZ AND comment "MKT " OR Description = "MKT " (with a space after MKT)

The issue is that I want only tickets returned that, in the comments and/or description, contain MKT as well as following text, not just MKT.

Does that work (will only search in XYZ project):

Project = XYZ AND (comment ~ "MKT" OR Description ~ "MKT")

Also you can use more generic query to search issue text fields for specific text:

Project = XYZ AND text ~ "MKT"
