Query an Array

Match an Array

To specify equality condition on an array, use the query document { <field>: <value> } where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document { <field>: <value> } where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document { <field>: <value> } where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, construct a filter using the Eq method, where <value> is the exact array to match, including the order of the elements:

Builders<BsonDocument>.Filter.Eq(<field>, <value>)

To specify equality condition on an array, use the query document eq( <field>, <value>) where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document eq( <field>, <value>) where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document { <field>: <value> } where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document { <field>: <value> } where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document { <field> => <value> } where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document [ <field> => <value> ] where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document { <field>: <value> } where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document { <field> => <value> } where <value> is the exact array to match, including the order of the elements.

To specify equality condition on an array, use the query document equal( <field>, <value> ) where <value> is the exact array to match, including the order of the elements.

The following example queries for all documents where the field tags value is an array with exactly two elements, "red" and "blank", in the specified order:

db.inventory.find( { tags: ["red", "blank"] } )

Copy the following filter into the Compass query bar and click Find:

{ tags: ["red", "blank"] }

mongoc_collection_t *collection;
bson_t *filter;
mongoc_cursor_t *cursor;
collection = mongoc_database_get_collection (db, "inventory");
filter = BCON_NEW (
   "tags", "[",
   BCON_UTF8 ("red"), BCON_UTF8 ("blank"),
   "]");
cursor = mongoc_collection_find_with_opts (collection, filter, NULL, NULL);

var filter = Builders<BsonDocument>.Filter.Eq("tags", new[] { "red", "blank" });
var result = collection.Find(filter).ToList();

cursor, err := coll.Find(
	context.TODO(),
	bson.D{{"tags", bson.A{"red", "blank"}}},
)

FindPublisher<Document> findPublisher = collection.find(eq("tags", asList("red", "blank")));

FindIterable<Document> findIterable = collection.find(eq("tags", asList("red", "blank")));

val findFlow = collection
    .find(eq("tags", listOf("red", "blank")))

cursor = db.inventory.find({"tags": ["red", "blank"]})

const cursor = db.collection('inventory').find({
  tags: ['red', 'blank']
});

$cursor = $db->coll("inventory")->find( { tags => [ "red", "blank" ] } );

$cursor = $db->inventory->find(['tags' => ['red', 'blank']]);

cursor = db.inventory.find({"tags": ["red", "blank"]})

client[:inventory].find(tags: ['red', 'blank'])

var findObservable = collection.find(equal("tags", Seq("red", "blank")))

If, instead, you wish to find an array that contains both the elements "red" and "blank", without regard to order or other elements in the array, use the $all operator:

db.inventory.find( { tags: { $all: ["red", "blank"] } } )

Copy the following filter into the Compass query bar and click Find:

{ tags: { $all: ["red", "blank"] } }

mongoc_collection_t *collection;
bson_t *filter;
mongoc_cursor_t *cursor;
collection = mongoc_database_get_collection (db, "inventory");
filter = BCON_NEW (
   "tags", "{",
   "$all", "[",
   BCON_UTF8 ("red"), BCON_UTF8 ("blank"),
   "]",
   "}");
cursor = mongoc_collection_find_with_opts (collection, filter, NULL, NULL);

var filter = Builders<BsonDocument>.Filter.All("tags", new[] { "red", "blank" });
var result = collection.Find(filter).ToList();

cursor, err := coll.Find(
	context.TODO(),
	bson.D{
		{"tags", bson.D{{"$all", bson.A{"red", "blank"}}}},
	})

findPublisher = collection.find(all("tags", asList("red", "blank")));

findIterable = collection.find(all("tags", asList("red", "blank")));

val findFlow = collection
    .find(all("tags", listOf("red", "blank")))

cursor = db.inventory.find({"tags": {"$all": ["red", "blank"]}})

const cursor = db.collection('inventory').find({
  tags: { $all: ['red', 'blank'] }
});

$cursor = $db->coll("inventory")->find( { tags => { '$all' => [ "red", "blank" ] } } );

$cursor = $db->inventory->find(['tags' => ['$all' => ['red', 'blank']]]);

cursor = db.inventory.find({"tags": {"$all": ["red", "blank"]}})

client[:inventory].find(tags: { '$all' => ['red', 'blank'] })

findObservable = collection.find(all("tags", "red", "blank"))
