Wildcard searching and regular expressions
Searching using the version order can be problematic because you need to use an existing version as a range limit. Sometimes you may also want to find issues with versions that contain a particular text in the version name. Fortunately, you can perform advanced version searches with JQL Search Extensions.
To search by wildcard, simply got go to Extended Search and execute issue in wildcardMatch("fixVersion", "v2.0*") to find all issues with versions starting with “v2.0”. You can put a wildcard anywhere in a search text.
