Returns multiple records by the values of a content_field. E.g. site.pages['custom_field_in_[test_value1,test_value2]'] returns all posts with post_type page and with the value of it’s content_field custom_field as test_value1 or test_value2.

E.g. site.pages['custom_field_in_[test_value1]'] will return all posts where the value for custom_field is test_value1
