<!-- Answer --> This is a known design limitation in HugeGraph 1.7.0. The difference in results between your two Gremlin queries comes from how HugeGraph's query planner handles filter placement and index enforcement. Filters directly after `g.E()` or `g.V()` are pushed into backend queries and require the property to be indexed, while filters inside `match()` or nested traversals are applied as in-memory predicates after data retrieval, bypassing index checks. This can lead to inconsistent results or exceptions compared to JanusGraph and TinkerPop, which do not enforce index requirements in the same way. For consistent behavior, ensure properties used in filters are indexed, or avoid placing filters inside `match()`/nested traversals when consistency is required. More details are documented in [GitHub issue #2929](https://github.com/apache/incubator-hugegraph/issues/2929). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
