Steps to Reproduce:

1. Have projects with sprints
2. Have Sprints that share some text (e.g. Sprint 1, QA Sprint 1, etc.)
3. Run the search:
   Project = X and Sprint = "Sprint 1"

Expected Results:

1. The search result should return only issues that have "Sprint 1" set.

Actual Results:

1. The search result is returning issues that contain that text on it (issues set with "Sprint 1" and "QA Sprint 1")

Workaround:

1. Use the sprint search by ID instead of name. E.g.:
   Project = X and Sprint = 123

Notes:
According to the documentation...

The "=" operator is used to search for issues where the value of the specified field exactly matches the specified value.

The Sprint field does not allow the "~" operator.
