Q: type hint for indexed operators
jexp opened this issue · comments
As Neo4j is schema free it's hard to reason about if an index can be used, that's why in Cypher (currently) you have to hint at the type, before an index is used e.g. for sorting, min/max aggregations etc.
Not sure if that's also true for parameters but could be.
e.g. MATCH (p:Person) RETURN p ORDER BY p.age
Will only use an index with the additional (numeric) type hint
e.g. MATCH (p:Person) WHERE p.age > 0 RETURN p ORDER BY p.age
we might need to find a way to support adding these type hints where necessary.
