Expressions

A Cypher^® expression is any part of a query that evaluates to a value. For details and examples of specific expressions, see the following sections:

Predicates
- Boolean operators: AND, OR, XOR, NOT
- Comparison operators: =, <>, <, >, <=, >=, IS NULL, IS NOT NULL
- List operators: IN
- String operators: STARTS WITH, ENDS WITH, CONTAINS, IS NORMALIZED, IS NOT NORMALIZED, =~
- Path pattern expressions: information about filtering queries with path pattern expressions.
- Type predicate expressions: information about how to verify the value type of a Cypher expression.
Node and relationship operators: information about how to access NODE and RELATIONSHIP property values with . and [].
Mathematical operators: +, -, *, /, %, ^.
String concatenation operators: +, ||
Temporal operators: +, -, *, /
List expressions: information about list concatenation operators (||, +), list element access, list slicing, and list as well as pattern comprehensions.
Map expressions: information about map operators (., []) and map projection.
Conditional expressions (CASE)

The following expressions are documented elsewhere in the Cypher Manual:

Expressions containing unsanitized user input may make your application vulnerable to Cypher injection. Consider using parameters instead. For more information, see Neo4j Knowledge Base → Protecting against Cypher Injection.
