The Enterprise Plan allows up to 50,000 searches per query, which is the highest search limit available. For people searches specifically, the Pro plan supports up to 50,000 profiles per search. There are no search limits beyond 50,000 available in any plan.
If you need any more help with search list sizes or anything else, please let me know. Would you like to share more about what you're trying to achieve or any other questions you have?
