Example 1: Retrieve all stores where the total sales is less than or equal to $35,000

db.stores.find({ "sales.totalSales": { "$lte": 35000 } }, {"_id": 1}, {"limit": 1})

This returns the following results:

{
  "_id": "e6895a31-a5cd-4103-8889-3b95a864e5a6"
}

Example 2: Find stores with 12 or fewer full-time staff

db.stores.find({ "staff.totalStaff.fullTime": { "$lte": 12 } }, {"name": 1, "staff.totalStaff.fullTime": 1}, {"limit": 1})

This returns the following results:

{
    "_id": "e6895a31-a5cd-4103-8889-3b95a864e5a6",
    "name": "VanArsdel, Ltd. | Picture Frame Store - Port Clevelandton",
    "staff": { "totalStaff": { "fullTime": 6 } }
}
