Escaping quotes and diacritics in Neo4j query

Question

Let's say I have the following query passed to Neo4j as string in a C#/.NET application:

MATCH (e)-[:BELONGS_TO]->(t:Tenant) WHERE t.id={id} AND ( e:Unit OR e:UnitInactive ) AND e.name contains {queryName} RETURN e

How do I format the query string to retrieve an specific e.name like "Mary's" or "João" , escaping quotes and diacritics and case-insensitive?

Answer 1

You can treat special characters (diacritics) as regular chars. Then single quote in Mary's can be escaped with \.

For example, in neo4j cypher:

 toLower(e.name) = "joão" OR toLower(e.name) = "mary\'s"
