Multiple Results Returned for API Call, But Only 1 Matched

[Abby Domanowski]

When executing a search via the API passing an email address, 2 results were returned even though only one of the email addresses was an exact match. Is it expected that, when submitting an exact email for account info, the API returns results that are not exact matches to the criteria?

Example call where the issue is present: <jiraURL>/rest/api/2/user/search?username=user%40domain.com&includeActive=True&includeInactive=False&maxResults=50
