Filter by minDate

[Pradye]

{ "_id": 1234, "thread_id": 3, "address": "2900", "person": -1, "date": 1365053816196,
}

Will the date attribute be unique (even diff in ms). Asking this because to fetch sms based on date filter by setting "minDate": lastReadDate +1

• lastReadDate = Store the latest sms date value.
• Not setting maxDate

Please advise if this would work.
