### Bug Type (问题类型) gremlin (结果不合预期) ### Before submit - [x] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 [FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents) ### Environment (环境信息) - Server Version: 1.7.0 - gremlin: 3.5.1 - Docker Image: `hugegraph/hugegraph:latest` - Backend: default Docker standalone backend - Data Size: 1 vertex, 0 edges ### Expected & Actual behavior (期望与实际表现) HugeGraph keeps a traverser for a `where()` child traversal whose `count()` is 0 and whose predicate is `lt(0)`. Minimal graph: (a:A {i: 1}) No R edges exist. Bug-triggering query: g.V('a').where(__.both('R').count().is(lt(0))).values('i') Expected: [] Actual: [1] Since the counted traversal returns 0, the predicate lt(0) should be false. ### Vertex/Edge example (问题点 / 边数据举例) ```javascript **Vertex/Edge example** curl -fsS --compressed -X DELETE \ "http://127.0.0.1:8080/graphs/hugegraph/clear?confirm_message=I'm%20sure%20to%20delete%20all%20data" curl -fsS --compressed -H 'Content-Type: application/json' -X POST \ -d '{"id":"a","label":"A","properties":{"i":1}}' \ "http://127.0.0.1:8080/graphs/hugegraph/graph/vertices"; ``` ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构) ```javascript **Schema** curl -fsS --compressed -H 'Content-Type: application/json' -X POST \ -d '{"name":"i","data_type":"LONG","cardinality":"SINGLE"}' \ "http://127.0.0.1:8080/graphs/hugegraph/schema/propertykeys"; curl -fsS --compressed -H 'Content-Type: application/json' -X POST \ -d '{"name":"A","id_strategy":"CUSTOMIZE_STRING","properties":["i"],"nullable_keys":["i"],"enable_label_index":true}' \ "http://127.0.0.1:8080/graphs/hugegraph/schema/vertexlabels"; curl -fsS --compressed -H 'Content-Type: application/json' -X POST \ -d '{"name":"B","id_strategy":"CUSTOMIZE_STRING","properties":[],"nullable_keys":[],"enable_label_index":true}' \ "http://127.0.0.1:8080/graphs/hugegraph/schema/vertexlabels"; curl -fsS --compressed -H 'Content-Type: application/json' -X POST \ -d '{"name":"R","source_label":"B","target_label":"A","frequency":"SINGLE","properties":[],"nullable_keys":[],"enable_label_index":true}' \ "http://127.0.0.1:8080/graphs/hugegraph/schema/edgelabels"; ``` -- This is an automated message from the Apache Git Service.
