Problem Statement

The customer would like to implement some regex when doing a query. For example

Printing all the servers with node in the name

[root@satellite ~]# hammer --no-headers --csv host list --fields name --search 'name ~ node'
node01.king.lab
node02.king.lab
node03.king.lab
node04.king.lab
node05.king.lab 

Now, let's try to filter all the machines with node in the name, but filtering values between 0 and 2

[root@satellite ~]# hammer --no-headers --csv host list --fields name --search 'name ~ node[0..2]'
[root@satellite ~]# 

[root@satellite ~]# hammer --no-headers --csv host list --fields name --search 'name ~ node[0-2]'
[root@satellite ~]# 

[root@satellite ~]# hammer --no-headers --csv host list --fields name --search 'name ~ node{0,2}'
[root@satellite ~]# 

As we can see above, the simple regex doesn't work when doing the query via hammer or webUI

User Experience & Workflow

The customer would like to create some regex to improve the filter.
