Pass operator (=, > or <) as a parameter in a Neo4j query - neo4j

Question

In this following query {op} raise a CypherException
#Query( "MATCH (p:NeoParticipant) " +
"WHERE toFloat(p.bmi) {op} toFloat({value}) " +
"RETURN p.participantId")
List<String> findParticipantsByBmi(#Param("op") String op,
#Param("value") String value);
Is there a way to pass an operator sign into a conditional statement?
Here the full stack

Answer 1

No, this is not possible. Only values can be substituted with placeholders.
