With the glob pattern, you can search for all versions matching a pattern. For example, you can write 2.* in the versions search box, and the website will show all the versions starting with "2." Some examples of what you can search:
2.*: will match all versions starting with 2.
3.*: will match all versions starting with 3.
4.1.*: will match all versions starting with 4.1
*: will match all versions
