Scenario: -
--> Try to filter JIRA with component which contains a particular text like “ABC”
i.e. using filter [component ~ "ABC"]

You will notice that JIRA will give error as below: -
“The operator '~' is not supported by the 'component' field.”

Let us say I have many components starting with ABC like : -
1) ABC-123
2) ABC-456
3) ABC-789
and so on.

If I want to filter JIRA using component field like [component ~ "ABC"]
It will give me above mentioned error.

To filter JIRA, I have to filter it using [component in ("ABC-123", "ABC-456", "ABC-789", ......... .....)], which is not user-friendly or I have to remember all components. If my admin has added few more, I would not know unless he/she tells me and I add those components in my already having filter with this in clause.

Another example is for https://jira.atlassian.com is , if I want to filter issues with component starting with/containing "Issue Navigation", I cannot do that.

So, there should be some way to filter component/labels using contains clause i.e. using ~
