This looks closely related to your other issue #3084 and likely shares the same root cause. HugeGraph uses a custom `HugeCountStrategy` (introduced in PR #2993 to replace TinkerPop's unsafe `CountStrategy`) that rewrites `count().is(...)` predicates for optimization [[1]](https://github.com/apache/hugegraph/pull/2993). A follow-up PR #3037 fixed handling of `ConnectiveStep` (`and()`/`or()`) child traversals within this strategy [[2]](https://github.com/apache/hugegraph/pull/3037). However, the specific combination of `NotP` wrapping a nested `ConnectiveP` — i.e., `not(outside(1,18).and(gte(0)))` — appears to be an uncovered edge case. Looking at the predicate conversion code in `TraversalUtil`, `NotP` is not explicitly handled in the `convHas2Condition()` method [[3]](https://github.com/apache/hugegraph/blob/9126c80e414c073b60fc074361b211cfb409e0eb/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/traversal/optimize/TraversalUtil.java#L350-L372), meaning the negation logic likely relies on TinkerPop's default handling, which may interact incorrectly with HugeGraph's count optimization rewriting. The relevant code is in: - [`HugeCountStrategy.java`](https://github.com/apache/hugegraph/pull/3037) — handles count optimization and `not()` rewriting for the `where()` pattern - [`TraversalUtil.java`](https://github.com/apache/hugegraph/blob/9126c80e414c073b60fc074361b211cfb409e0eb/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/traversal/optimize/TraversalUtil.java) — handles predicate conversion, including `convAnd()` and `convOr()` for compound predicates Since PR #3037 was merged on 2026-06-08 and the `hugegraph/hugegraph:latest` Docker image you're using is version 1.7.0, you may not have this fix. But even with that PR, the `NotP` + nested `ConnectiveP` combination (`not(outside().and())`) doesn't appear to be covered by the added tests (`testConnectiveAndCountIsZero`, `testConnectiveOrCountIsZero`). This is likely a gap in the `HugeCountStrategy` rewriting logic when it encounters `NotP` containing a `ConnectiveP` child — the negation isn't correctly propagated through the compound predicate during the count optimization pass. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fhugegraph).* --- Share context across your team and agents.
