Optional Match for 7th September

QUERY 1

is a short version of the one I have opened for your performance comments. It contains two OPTIONAL MATCH and works without a WITH statement. It also doesn't need the nodes specified on the RETURN statement for them to be displayed.

QUERY 2

Is a refined version, replacing the SHORTESTPATH with a more specific relationship. It has many OPTIONAL MATCH statements, but even when there are only a couple, it requires a WITH statement for parameters to be found on the RETURN statement.

OPTIONAL MATCH (p11fa:Person), (p11fb:Person), 
r11fb = shortestPath((p11fb)-[*..3]-(p11fa))
WHERE p11fa.name = "Monson, Lady Anne" and
p11fb.name = "Solander, Daniel" 

WITH p11fa, r11fb, p11fb

WHERE o11f.name = "Monson Bengal Insect Collection"

WITH p11fa, r11fb, p11fb, o11f, r11fa
OPTIONAL MATCH (o11f)-[r11fc]->(p11fc:Person)

OPTIONAL MATCH 
(p11fa2:Person)-[r11fd:Kin]->(p11fd:Person)
WHERE p11fa2.name = "Monson, Lady Anne" and p11fd.name = "Vane, William Harry, 1st Duke of Cleveland"
