如何在Neo4J 3.x中构建Cypher/APOC查询，该查询搜索两种不同的关系类型？

目前，我使用以下Cypher/APOC查询按特定属性（

user

id）搜索关系类型

to

：

我希望不仅可以搜索索引

to

，还可以搜索索引

AT

（

AT

类型的关系），以便生成的

rel

参数同时包含

to

和

AT

关系

我可以想象它会像添加

或
操作符一样简单，如下所示：

CALL apoc.index.relationships('TO','user:16c01100-aa92-11e3-a3f6-35e25c9775ff') OR
apoc.index.relationships('AT','user:16c01100-aa92-11e3-a3f6-35e25c9775ff') YIELD rel, start, end
WITH DISTINCT rel, start, end
MATCH (ctx:Context)
WHERE rel.context = ctx.uid
RETURN DISTINCT start.uid AS source_id,
start.name AS source_name,
end.uid AS target_id,
end.name AS target_name,
rel.uid AS edge_id,
ctx.name AS context_name,
rel.statement AS statement_id,
rel.weight AS weight;

但它不起作用

也许我可以做点什么，从这两个apoc中得到
rel
s，然后简单地把它们合并成一个
rel
，但我真的不知道怎么做。。。或者也许有一种更简单的方法我看不出来？
子句的用法如何：

您可以通过以下方式完成：

工作得很有魅力。非常感谢。
CALL apoc.index.relationships('TO','user:16c01100-aa92-11e3-a3f6-35e25c9775ff') OR
apoc.index.relationships('AT','user:16c01100-aa92-11e3-a3f6-35e25c9775ff') YIELD rel, start, end
WITH DISTINCT rel, start, end
MATCH (ctx:Context)
WHERE rel.context = ctx.uid
RETURN DISTINCT start.uid AS source_id,
start.name AS source_name,
end.uid AS target_id,
end.name AS target_name,
rel.uid AS edge_id,
ctx.name AS context_name,
rel.statement AS statement_id,
rel.weight AS weight;

CALL apoc.index.relationships('TO','user:16c01100-aa92-11e3-a3f6-35e25c9775ff') YIELD rel, start, end
WITH DISTINCT rel, start, end
MATCH (ctx:Context)
WHERE rel.context = ctx.uid
RETURN DISTINCT start.uid AS source_id,
start.name AS source_name,
end.uid AS target_id,
end.name AS target_name,

ctx.name AS context_name,
rel.statement AS statement_id,
rel.weight AS weight
UNION
