How can I do a one-to-one search in the title field?

Hi,

Field3 doesn't have a raw field type, it only has text;

"properties" : { 
               "Field3" : { 
                  "type" : "text" 
                } 
          }

You do not need to put .raw at the end there, you are using the text field.
