Following is the behavior which I would prefer for different cases:

1. query criteria with name N1 with conditions C1 exists, and user tries to save another query criteria with the name N2 and condition C2 --> we directly save the new query criteria
2. issues/8913: query criteria with name N1 with conditions C1 exists, and user tries to save another query criteria with the same name N1 with conditions C2 --> we prompt the user if they would like to overwrite conditions C1 with C2
3. This issue: query criteria with name N1 with conditions C1 exists, and user tries to save another query criteria with the name N2 but with same condition C1 --> we prompt the user if they would like to rename query criteria N1 to N2
4. query criteria with name N1 with conditions C1 exists, and user tries to save another query criteria with the same name N1 with same conditions C1 --> inform the user that query criteria with same name and conditions already exist
5. This issue: query criteria with name N1 with conditions C1 exists, and user tries to save another query criteria with the exist name N2 but with same condition C1 --> we prompt the user

I know this will complicate the logic a bit. But, I feel it will resolve the issue fully.

Thanks
