Contact Reference field search not finding all records - Does not include First Name, Last Name and

I created a UI field that references the Contact record. I have tested every combination of {{Name}}, {{First Name}} {{Middle}} {{Last Name}} {{Name__c}}, in the Search and Display components and I am not getting the search results that I want.

Some combinations allow me to find  Mary A Poppins, but not Mary Poppins.  Another combination allows me to find Mary Poppins, but not Mary A Poppins. I want to enter Mary Poppins and see Mary Poppins and Mary A Poppins.  I even created a Contact Lookup on the sObject and added that to the page, and the same thing is happening. What am I doing wrong?

Thanks in advance

I found the problem. I needed to Tokenize autocomplete search.
