MongoDB-specific operators
Exists
Matches documents that have the specified field.
php
User::where('age', 'exists', true)->get();
All
Matches arrays that contain all elements specified in the query.
php
User::where('roles', 'all', ['moderator', 'author'])->get();
Size
Selects documents if the array field is a specified size.
php
Post::where('tags', 'size', 3)->get();
Regex
Selects documents where values match a specified regular expression.
php
use MongoDB\BSON\Regex;
User::where('name', 'regex', new Regex('.*doe', 'i'))->get();
NOTE: you can also use the Laravel regexp operations. These are a bit more flexible and will automatically convert your regular expression string to a MongoDB\BSON\Regex object.
php
User::where('name', 'regexp', '/.*doe/i')->get();
The inverse of regexp:
php
User::where('name', 'not regexp', '/.*doe/i')->get();
Type
Selects documents if a field is of the specified type. For more information check: http://docs.mongodb.org/manual/reference/operator/query/type/#op._S_type
php
User::where('age', 'type', 2)->get();
Mod
Performs a modulo operation on the value of a field and selects documents with a specified result.
php
User::where('age', 'mod', [10, 0])->get();
