[BUG] Syntax error using logical operator OR (original) (raw)

We discovered a bug that Syntax error using logical operator OR.

We want to use logical operator OR to merge two individual queries, but it trigger a syntax exception which I think the query it's actually correct. And I keep triggering this kind of problem.
Here is one of our examples that triggered the bug.

  1. g.V().in('el2','el4') is a correct query.
  2. g.V().has('vp1') is a correct query.
  3. g.V().or(in('el2','el4'),has('vp1')) is supposed to be a correct query but trigger a crash.

Expected behavior:

No exception should be expected to throw.

Actual behavior:

A exception is thrown. And I'm not really sure whether this problem should happen so I report this. And I think if I replace the in into inE here, the bug may not be triggered, but I read the Gremlin manual carefully, this query syntax is correct and should be supported.

java.util.concurrent.ExecutionException: org.apache.tinkerpop.gremlin.driver.exception.ResponseException: startup failed:
Script861.groovy: 1: unexpected token: in @ line 1, column 10.
   g.V().or(in('el2','el4'),has('vp1'))
