Perform static computations outside of the query

It is recommended to resolve static computations (simple mathematical/string operations) on the client-side. Consider this example where you want to find all people one year older or less than the author: 

MATCH (m:Message)-[:HAS_CREATOR]->(p:person)
WHERE p.age <= ($age + 1)
RETURN m

Here, $age is injected into the query via parameters, and is then added to a fixed value. This value is then compared with p.age. Instead, a better approach would be doing the addition on the client-side and passing the calculated value as a parameter $ageplusone. This helps the query engine to create optimized plans, and avoids static computation for each incoming row. Following these guidelines, a more efficient verson of the query would be: 

MATCH (m:Message)-[:HAS_CREATOR]->(p:person)
WHERE p.age <= $ageplusone
RETURN m
