Great question — variable-length paths are fully supported in the query builder: # Friends of friends (1 to 3 hops) stmt = select().match(
(User.alias("a"), FRIEND.variable_length(1, 3), User.alias("b"))
).where(
User.alias("a").user_id == 1
).returns(
User.alias("b")
)
Generates: `(a)-[:FRIEND1..3]->(b)`*Variants:*
- Unbounded: `FRIEND.variable_length()` → ``
- Exact length: `FRIEND.variable_length(2, 2)` → `2`
- Min only: `FRIEND.variable_length(1)` → `1..`
- Range: `FRIEND.variable_length(1, 3)` → `*1..3` You can also use the explicit `VariableLength(FRIEND, 1, 3)` constructor if you need to alias the path or reference it later in the query. The builder handles all edge cases (empty paths, cycles) the same way RedisGraph does — we compile to idiomatic Cypher without abstraction leaks. Raw string patterns still work if you need something exotic. |
