hasAll( )

Refines a query to match items whose specified property contains all of the specified values.

The hasAll() function refines a PostsQueryBuilder to match only items where the value of the specified propertyName equals all of the specified values. Matching strings with hasAll() is case-sensitive, so 'text' isn't equal to 'Text'. If the specified property is an array, hasAll() matches if that array's elements match all of the specified values.
