Is there a limit to the amount of contacts that can be searched for on Existing Contact using autocomplete on a Drupal Webform? I have 1+million contacts. If I restrict the webform to a group with a limited number of contacts the autocomplete works well. However, if I do not restrict to a small group the autocomplete fails and wants to create a new contact.
The autocomplete works and does not have a limitation (we have 900k contacts and no problems). My mistake was in the selection of the Contact Display Field for the Existing Contact on the Drupal WebForm. I was using the "Display Name" as the structure but I was entering search as if it was the "Sort Name" I was getting unexpected results. Once I started entering the search with the correct format the results were as expected and all the contacts are included.
