for clone detection purpose, copy-paste your @matches in Notepad++ or similar and
1. replace https to *
2. replace http to *
3. may be better to replace www. to *
4. replace *:// to *://*
5. replace *://**. to *://*
6. replace *://** to *://*
7. sort all @matches by a-z (use Edit - Line Operations - Sort Lines Lexicographically Ascending)
