此问题在此处已有答案：

Neo4j return nodes connected by relationships of a given label and property（2个答案）
26天前关闭。
我怀疑我遇到了一个bug，使用Go SDK查询时，得到的数据结果与Neo4j浏览器中的不一致，缺少几个Relationship。
Neo4j版本：Neo4j内核5.12.0社区
Neo4j模式：单示例
驱动程序版本：Go driver v5.12.0
操作系统：centos

我用来处理从Neo4j返回的数据的代码如下。

result, session, err := global.Neo4j.RunCypherQuery(body.Cypher, nil)
    if err != nil {
        logger.Log.Error("RunCypherQuery error: " + err.Error())
        response := responses.NewErrorResponse(responses.StatusCodeUnknownErr, err.Error())
        c.JSON(http.StatusOK, response)
        return
    }

    var nodes []neo4j.Node
    var relationships []neo4j.Relationship

    seenNodes := make(map[int64]bool)
    seenRelationships := make(map[int64]bool)
    for result.Next() {
        record := result.Record()
        for _, value := range record.Values {
            if value == nil {
                continue
            }
            switch v := value.(type) {
            case neo4j.Node:
                if _, found := seenNodes[v.Id]; !found {
                    seenNodes[v.GetId()] = true
                    nodes = append(nodes, v)
                }
            case neo4j.Relationship:
                if _, found := seenRelationships[v.Id]; !found {
                    seenRelationships[v.GetId()] = true
                    relationships = append(relationships, v)
                }
            case neo4j.Path:
                for _, node := range v.Nodes {
                    if _, found := seenNodes[node.Id]; !found {
                        seenNodes[node.GetId()] = true
                        nodes = append(nodes, node)
                    }
                }
                for _, rel := range v.Relationships {
                    if _, found := seenRelationships[rel.Id]; !found {
                        seenRelationships[rel.GetId()] = true
                        relationships = append(relationships, rel)
                    }
                }
            case []interface{}:
                for _, item := range v {
                    switch elem := item.(type) {
                    case neo4j.Node:

                        }
                    case neo4j.Relationship:

                            seenRelationships[elem.GetId()] = true
                            relationships = append(relationships, elem)
                        }
                    default:
                        logger.Log.Error("Unexpected type in []interface{}: %T", item)
                        response := responses.NewErrorResponse(responses.StatusCodeUnknownErr, errors.New(fmt.Sprintf("Unexpected type in []interface{}: %T", item)).Error())

                return
            }
        }
    }

func (c *Client) RunCypherQuery(query string, params map[string]interface{}) (neo4j.Result, neo4j.Session, error) {
    session := c.driver.NewSession(neo4j.SessionConfig{})
    fmt.Println(query)
    result, err := session.Run(query, params)
    if err != nil {
        return nil, session, err
    }
    return result, session, nil
}

的数据
在neo4j桌面搜索结果是

的数据
在我代码中搜索结果是

的
标有红色“X”的位置表示未找到结果。
在RunCypherQuery方法中，在返回的结果中找不到这三个Relationship的数据。
