You can count the number of documents returned by a query by calling the ``where()`` and
21+
``count()`` methods on a collection of models or a query builder.
22+
23+
To return the number of documents that match a filter, pass the query filter to the ``where()``
24+
method and call the ``count()`` method.
25+
26+
Example
27+
-------
28+
29+
This usage example performs the following actions:
30+
31+
- Uses the ``Movie`` Eloquent model to represent the ``movies`` collection in the
32+
``sample_mflix`` database
33+
- Counts the documents from the ``movies`` collection that match a query filter
34+
- Prints the matching document count
35+
36+
The example calls the following methods on the ``Movie`` model:
37+
38+
- ``where()``: Matches documents in which the value of the ``genres`` field includes ``"Biography"``.
39+
- ``count()``: Counts the number of matching documents. This method returns an integer value.
