Does anyone know why in a JQL search Jira complexly ignores underscores "_" Their was a ticket that was missing in a search today "project in CAP and Summary ~1718" and it ignored a ticket that had CR 1718_" in it. When he added the underscore in the query, it still ignored it. We fixed it in the summary of the ticket itself, and it picked it up fine.
We were just curious if Jira has reserved special characters that will be ignored in searches if used (besides underscores). We should avoid using them in labels, summaries, etc.
Thanks!
