+ * Get entities based on their private data, in a similar way to metadata.

+ * @param string $name The name of the setting
+ * @param string $value The value of the setting
+ * @param string $type The type of entity (eg "user", "object" etc)
+ * @param string $subtype The arbitrary subtype of the entity
+ * @param int $owner_guid The GUID of the owning user
+ * @param string $order_by The field to order by; by default, time_created desc
+ * @param int $limit The number of entities to return; 10 by default
+ * @param int $offset The indexing offset, 0 by default
+ * @param boolean $count Set to true to get a count rather than the entities themselves (limits and offsets don't apply in this context). Defaults to false.
+ * @param int $site_guid The site to get entities for. Leave as 0 (default) for the current site; -1 for all sites.
+ * @param int|array $container_guid The container or containers to get entities from (default: all containers).
+ * @return array A list of entities.
