Default_operator trouble

Hey

Trying to figure out how to use the default_operator using a URI request.
I'm searching for words / phrases in two different keys:

  • Search for firstName contains "John"
    AND
  • Search for note contains "Some testnotes"

See query below:

/contacts/_search?q=+firstName:John+note:some%20testnotes&default_operator=AND

However, elasticsearch returns records where "some" and "testnotes" are found separately in the "note" key.
How can I solve this?

TIA
