query condition on fields in an embedded/nested document, use dot notation ("field.nestedField").
When querying using dot notation, the field and nested field must be inside quotation marks.
The following example selects all documents where the field uom nested in the size field equals "in":
db.inventory.find( { "size.uom": "in" } )Copy the following filter into the Compass query bar and click Find:
mongoc_collection_t *collection;bson_t *filter;mongoc_cursor_t *cursor;collection = mongoc_database_get_collection (db, "inventory");filter = BCON_NEW ("size.uom", BCON_UTF8 ("in"));cursor = mongoc_collection_find_with_opts (collection, filter, NULL, NULL);var filter = Builders<BsonDocument>.Filter.Eq("size.uom", "in");var result = collection.Find(filter).ToList();cursor, err := coll.Find( context.TODO(), bson.D{{"size.uom", "in"}},)findPublisher = collection.find(eq("size.uom", "in"));findIterable = collection.find(eq("size.uom", "in"));val findFlow = collection .find(eq("size.uom", "in"))cursor = db.inventory.find({"size.uom": "in"})const cursor = db.collection('inventory').find({ 'size.uom': 'in'});$cursor = $db->inventory->find(['size.uom' => 'in']);cursor = db.inventory.find({"size.uom": "in"})client[:inventory].find('size.uom' => 'in')findObservable = collection.find(equal("size.uom", "in"))In addition to the equality filter, MongoDB provides various query operators to specify filter conditions. Use the FilterDefinitionBuilder methods to create a filter document. For example:
var builder = Builders<BsonDocument>.Filter;builder.And(builder.Eq(<field1>, <value1>), builder.Lt(<field2>, <value2>));In addition to the equality condition, MongoDB provides various query operators to specify filter conditions. Use the com.mongodb.client.model.Filters helper methods to facilitate the creation of filter documents. For example:
and(gte(<field1>, <value1>), lt(<field2>, <value2>), eq(<field3>, <value3>))In addition to the equality condition, MongoDB provides various query operators to specify filter conditions. Use the com.mongodb.client.model.Filters helper methods to facilitate the creation of filter documents. For example:
and(gte(<field1>, <value1>), lt(<field2>, <value2>), eq(<field3>, <value3>))In addition to the equality condition, MongoDB provides various query operators to specify filter conditions. Use the com.mongodb.client.model.Filters helper methods to facilitate the creation of filter documents. For example:
and(gte(<field1>, <value1>), lt(<field2>, <value2>), eq(<field3>, <value3>))In addition to the equality condition, MongoDB provides various query operators to specify filter conditions. Use the com.mongodb.client.model.Filters_ helper methods to facilitate the creation of filter documents. For example:
and(gte(<field1>, <value1>), lt(<field2>, <value2>), equal(<field3>, <value3>))The following query uses the less than operator ($lt) on the field h embedded in the size field:

To specify an equality condition on a field that is an embedded/nested document, use the query filter document { <field>: <value> } where <value> is the document to match.
To specify an equality condition on a field that is an embedded/nested document, use the query filter document { <field>: <value> } where <value> is the document to match.
To specify an equality condition on a field that is an embedded/nested document, construct a filter using the Eq method, where <value> is the document to match:
Builders<BsonDocument>.Filter.Eq(<field>, <value>)To specify an equality condition on a field that is an embedded/nested document, use the filter document eq( <field1>, <value>) where <value> is the document to match.
To specify an equality condition on a field that is an embedded/nested document, use the filter document eq( <field1>, <value>) where <value> is the document to match.
To specify an equality condition on a field that is an embedded/nested document, use the query filter document { <field>: <value> } where <value> is the document to match.
To specify an equality condition on a field that is an embedded/nested document, use the query filter document { <field>: <value> } where <value> is the document to match.
To specify an equality condition on a field that is an embedded/nested document, use the query filter document [ <field> => <value> ] where <value> is the document to match.
To specify an equality condition on a field that is an embedded/nested document, use the query filter document { <field>: <value> } where <value> is the document to match.
To specify an equality condition on a field that is an embedded/nested document, use the query filter document { <field> => <value> } where <value> is the document to match.
To specify an equality condition on a field that is an embedded/nested document, use the filter document equal( <field1>, <value> ) where <value> is the document to match.
For example, the following query selects all documents where the field size equals the document { h: 14, w: 21, uom: "cm" }:
db.inventory.find( { size: { h: 14, w: 21, uom: "cm" } } )Copy the following filter into the Compass query bar and click Find:

For example, the following query does not match any documents in the inventory collection:
db.inventory.find( { size: { w: 21, h: 14, uom: "cm" } } )mongoc_collection_t *collection;bson_t *filter;mongoc_cursor_t *cursor;collection = mongoc_database_get_collection (db, "inventory");filter = BCON_NEW ( "size", "{", "w", BCON_DOUBLE (21), "h", BCON_DOUBLE (14), "uom", BCON_UTF8 ("cm"), "}");cursor = mongoc_collection_find_with_opts (collection, filter, NULL, NULL);var filter = Builders<BsonDocument>.Filter.Eq("size", new BsonDocument { { "w", 21 }, { "h", 14 }, { "uom", "cm" } });var result = collection.Find(filter).ToList();cursor, err := coll.Find( context.TODO(), bson.D{ {"size", bson.D{ {"w", 21}, {"h", 14}, {"uom", "cm"}, }}, })findPublisher = collection.find(eq("size", Document.parse("{ w: 21, h: 14, uom: 'cm' }")));findIterable = collection.find(eq("size", Document.parse("{ w: 21, h: 14, uom: 'cm' }")));val findFlow = collection .find(eq("size", Document.parse("{ w: 21, h: 14, uom: 'cm' }")))cursor = db.inventory.find({"size": SON([("w", 21), ("h", 14), ("uom", "cm")])})const cursor = db.collection('inventory').find({ size: { w: 21, h: 14, uom: 'cm' }});$cursor = $db->inventory->find(['size' => ['w' => 21, 'h' => 14, 'uom' => 'cm']]);cursor = db.inventory.find({"size": {"w": 21, "h": 14, "uom": "cm"}})client[:inventory].find(size: { h: 21, w: 14, uom: 'cm' })findObservable = collection.find(equal("size", Document("w" -> 21, "h" -> 14, "uom" -> "cm")))Queries that use comparisons on embedded documents can result in unpredictable behavior when used with a driver that does not use ordered data structures for expressing queries.
The example in this section uses the sample movies dataset. To learn how to load the sample dataset into your MongoDB Atlas deployment, see Load Sample Data.
To query an embedded document in MongoDB Atlas, follow these steps:
Warning Navigation Improvements In ProgressWe're currently rolling out a new and improved navigation experience. If the following steps don't match your view in the Atlas UI, see the preview Atlas documentation.
If it's not already displayed, select the organization that contains your desired project from the Organizations menu in the navigation bar.
If it's not already displayed, select your project from the Projects menu in the navigation bar.
If it's not already displayed, click Clusters in the sidebar.
The Clusters page displays.
For the cluster that contains the sample data, click Browse Collections.
In the left navigation pane, select the sample_mflix database.
Select the movies collection.
Specify the query filter document in the Filter field. A query filter document uses query operators to specify search conditions.
Copy the following query filter document into the Filter search bar:
This query filter returns all documents in the sample_mflix.movies collection where the embedded document for the awards field contains { wins: 1 }.
