JIRA Quick search for numerical portion of a string in an issue

[Derek Sheeman]

I am trying to figure out how to search for tickets containing this string somewhere in a comment:

PO62612071

The problem is, that I don't know that the user has attached the letters PO to the string, so I need to be able to find it with queries on 62612071.

I get various errors when attempting to do quick searches on 62612071

"62612071", /62612071 /*62612071 *62612071 etc all don't work for various reasons.

Is there a way to search on a numerical portion of a string from quick search?

Using JIRA 6.3.3

I am also interested here, I am unable to find a method to search for this query.
