Summary

When searching for issues in the Parent Link field on the create and edit issue screens in JIRA, the search only matches entire words or the entire issue key.

Same behavior was found a few years ago when the UI was using the old issue view. Reported under bug https://jira.atlassian.com/browse/JSWCLOUD-19247 now replicated in the new issue view.

Steps to Reproduce

1. Configure a new level in Portfolio Hierarchy Configuration
2. Add the Parent Link field to the Create or Edit screen in JIRA
3. Create a new issue of the Issue Type configured for the new level
4. Create or edit an epic and attempt to search for the issue created in step 3 in the Parent Link field in JIRA

Expected Results

Partial text searches will match the issue. I.E. for an issue of TEST-1 This is a test parent issue, Typing "T" should match as would "p" or "par".

Actual Results

Partial text searches will not match the issue, only typing the entire word or issue will will match:

For an issue of TEST-1 This is a test parent issue

• "T" - No matches
• "p" - No matches
• "par" - No matches
• "TEST-1" - Matches
• "This" - Matches
• "parent" - Matches

Workaround

Do an exact match on an issue key, or use a wildcard ( * ) to search the summary text.
