我可以使用WordPress meta_query的数组是否有限制？

Question

I'm trying to make a custom search form where each post has custom meta data. When I filter by two key values I can get the results I search for. But when I add a third array, amenities, the results don't appear.

I'm wondering if I can only pass two arrays within the meta_data argument. I don't know just guessing.

Here is my query argument:

    $args_listings = array( 
        'cat' => 'listings',
        'meta_query' => array(
                array(
                    'key'     => 'neighborhood',
                    'value'   => $neighborhoodlist,
                    ),
                array(
                    'key'     => 'bedrooms',
                    'value'   => $bedroomnum,
                    ),
                array(
                    'key'     => 'amenities',
                    'value'   => $amenitieslist,
                    ),
        ),

    );

</div>
