+The part after `+shortest` can also take a parameter if it is a record ID. The following example will return the same result as the previous one.
+
+```surql
+LET $you = SELECT VALUE id FROM ONLY person WHERE name = 'you' LIMIT 1;
+LET $star = SELECT VALUE id FROM ONLY person WHERE name = 'star' LIMIT 1;
+$you.{..+shortest=$star}->knows->person;

 #### +collect
 
 Using `+collect` will collect all of the unique collected records. As this collection is created by moving recursively one level at a time, the output will show the closest connections first and least close connections at the end.
