Neo4j Cypher查詢失敗，並返回一個未知的錯誤

我想構建一個Cypher查詢來測試是否存在特定的結構，因此我可以將日期與它關聯。Neo4j Cypher查詢失敗，並返回一個未知的錯誤

運行的Neo4j 2.1.0-M01在Linux服務器上，而是發生與Neo4j的2.0.1

我們開始用乾淨的數據庫，0節點的相同問題。

首先我運行這個MATCH查詢來證明它運行。顯然這個查詢不會返回任何節點。但是在創建節點後，將會發生失敗並顯示「未知錯誤」。對我來說這看起來像一個bug，因爲具有較少節點的查詢將返回。有沒有人有建議如何現在重寫這個查詢？

對不起，這個帖子中有大量的代碼。

感謝，

你MATCH查詢方式複雜。沒有必要指定每個節點。以下查詢返回羣集及其相關控制器：

MATCH (c:Cluster{cluster_name:'mycluster',cluster_uuid:'7bd4f66d-5faf-11db-8d0d-000e0cba569c'})<-[:IS_PART_OF_CLUSTER]-(sc:Controller) 
WITH c, collect(sc) as controllers 
RETURN c as cluster, controllers

感謝您的回覆。這確實是一個複雜的查詢。但是這是必須的，因爲我們需要測試這個具有所有這些控制器的特定集羣是否已經存在。如果集羣已經存在，那麼我們將更新'最後'或'第一個'報告日期，如果需要，將pointint更新到集羣節點。如果此特定羣集配置尚不存在，那麼我們將使用開始日期和結束日期來創建它。 – user3323098
