You can nest logical operators to filter better and arrive at match candidates.

Nesting of logical operators allows you to form complex boolean logic within your match group.

Sample use of the nesting of logical operators is as follows:

                    "label": "(Fuzzy) AddressLine1, (Exact) Name, City, State, (Equals) Shipping",
