Using wildcard * and % not returning expected results in JQL search

Issue Summary

Use of multi character wildcard % or * not returning expected results when used in the middle of the term in JQL search

Steps to Reproduce

For issues with the summary of Test ABC-ISSUE and TEST DE1-ISSUE:

• query with Job *-ISSUE
• query with Job %-ISSUE

Similarly occurs when no dash is present after wildcard:
For issues with the summary of Test ABCISSUE and Test DE1Issue:

• query with Test *ISSUE
• query with Test %ISSUE

Expected Results

For wildcard queries using * or % to return any result matching the rest of the query.
In given instances to return all issues with the summary of Test ABC-ISSUE and TEST DE1-ISSUE, or with the summary of Test ABCISSUE and Test DE1Issue

Actual Results

For issues with the summary of Test ABC-ISSUE and TEST DE1-ISSUE:

• using the search query of Job *-ISSUE returns no results
• using Job %-ISSUE only returns the issues with Test ABC-ISSUE and not TEST DE1-ISSUE

Similarly occurs when no dash is present after wildcard:
For issues with the summary of Test ABCISSUE and Test DE1Issue:

• using the search query of Test *ISSUE returns no results
• using Test %ISSUE only returns the issues with Test ABC-ISSUE and not TEST DE1-ISSUE

Other Examples:

_ABC-FVG-003 _- Results with value ABC-FVG-003 as expected

"ABC-NR1*" - Results in all values that begin with ABC-NR1* as expected

"ABC-FVG*" - Does not return anything. Using "ABC?FVG*" or "ABC*FVG*" doesn't have any result.

But "ABC FVG*" - Return's needed result. And variant "ABC FVG-*" works fine.

Workaround

Modify query to remove the characters after the wildcard: Test * returns all expected results
