Hello Daniel! The exclude companies search filters only works with company search tables. Here, I suggest the following:
- make the new company search without excluding any companies
- do a lookup to your other table to check the search found duplicate companies
For future searches, you can filter this table by that lookup enrichment and now you have a company search table with companies that you can exclude in other searches.
Feel free to send the table of companies you would like to exclude and the company search filters you'd like and I can show an example of what I mean in your workspace.
