 /**
- * Retrieve a site object by its domain and path.
+ * Retrieve the closest matching site object by its domain and path.
+ * 
+ * This will not necessarily return an exact match for a domain and path. Instead, it
+ * breaks the domain and path into pieces that are then used to match the closest
+ * possibility from a query.
+ *
+ * The intent of this method is to match a site object during bootstrap for a
+ * requested site address
  *
  * @since 3.9.0
  * @since 4.7.0 Updated to always return a `WP_Site` object.
