Title: Improved query building

In MongoDB the way you handle string vs numerics is somewhat different from php.

i.e.: if you search for a phone number: { "workPhone": "+367061546843" } is different { "workPhone": +367061546843 }

is_numeric returns true for a string containing numbers, but will mongo handle it as a string.
