Why isn't my filter on arrays working?

"people":[ "firstname": "Jimmie", "lastname": "Barninger", "zip_code": 12345 , 
            "firstname": "John", "lastname": "Doe", "zip_code": null]

You will get matches for individual people in the array who only match one of your filters i.e. "firstname:Jimmie" "lastname":"Doe" will return the above record. 

One way to solve this issue is by breaking down the record like this. 

"people1":{ 
    "firstname": "Jimmie",
    "lastname": "Barninger",
    "zip_code": 12345 },
"people2":{ 
     "firstname": "John",
    "lastname": "Doe",
    "zip_code": null}
