What is the most effective way to filter individuals based on their place of residence in MongoDB?

I am managing a database containing over 800 documents, each with detailed information about individuals such as:

"_id" : ObjectId("5adf3c1544abaca147cdd399"),

"index" : 80,

"guid" : "ff1c8885-80fc-41de-a6e2-5a59ccd206e9",

"isActive" : true,

"balance" : "$2,249.41",

"picture" : "http://placehold.it/32x32",

"age" : 32,

"eyeColor" : "blue",

"name" : "Lenora Hayden",

"gender" : "female",

"company" : "FIREWAX",

"email" : "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="85e9e0ebeaf7e4ede4fce1e0ebc5e3ecf7e0f2e4fdabe6eae8">[email protected]</a>",

"phone" : "+1 (861) 457-2612",

"address" : "554 Bridge Street, Elbert, New Hampshire, 5327",

"about" : "Laborum id anim in ad officia duis est sunt ipsum cupidatat Lorem. Id non excepteur proident id aliqua ea ipsum enim. Sint velit enim proident dolore eiusmod aliqua velit elit id in deserunt. Sint ut magna et quis commodo aliquip consequat Lorem laboris sunt proident aute duis tempor.\r\n",

"registered" : "2014-03-27T09:37:45 -02:00",

"latitude" : -64.083596,

"longitude" : 13.025292,

"tags" : [
               "tempor",
               "velit",
               "do",
               "esse",
               "sunt",
               "enim",
               "eiusmod"
],

"friends" : [
                {
                        "id" : 0,
                        "name" : "Meadows Allen"
                },
                {
                        "id" : 1,
                        "name" : "Riggs Brown"
                },
                {
                        "id" : 2,
                        "name" : "Kris Fuller"
                }
        ],

"greeting" : "Hello, Lenora Hayden! You have 1 unread messages.",

"favoriteFruit" : "banana"

I am looking to sort and group the people based on their state of residence, specifically those living in New Hampshire.

db.usersdb.aggregate({$group: {_id: "$address"}}).pretty()

I want to apply filters to only target addresses. How can I identify individuals residing in a specific state and filter them accordingly?

Answer №1

If you want to narrow down your collection, make sure to include a $match stage for filtering purposes.

The $match stage serves as criteria for querying your collection, with the resulting data being processed in subsequent stages.
