How to find new sites for the Indexer please?

Hello,

Today I have reinstalled my old Scrapebox(after 5 years) as I wanted to index specific urls.

I noticed that the Rapid indexer list that comes with Scrapebox is outdated and many links are dead.

I would like to find a new list of these links but cannot work out how to do it?

Could someone please tell me how to do it?

I tried in the harvester:
inurl:domain=

I thought Scrapebox would look for urls parameters looking for this but instead it asked me some keywords.
Is there a way to just look for url parameters without keywords?

Thank you so much,
