我有一个查询，该查询可能返回大量行。尽可能快是至关重要的。
我当前的查询显示由于过滤器折线而使节点加倍，我该如何做才能显示n.NAME呢？
PS：PS：如果我删除：-> extract(n in segments | n.ORIGIN_POLYLINE) as polylines,，那么我有很好的结果，但是我想让折线具有唯一的节点（请参见图片：1和2）
这是我的查询：
MATCH (p:Polyline_ROMANIA)-[:CONTAINS_ROMANIA]->(n:Point_ROMANIA)
WHERE p.ID_POLYLINE='9141'
WITH head(COLLECT(n)) as start
MATCH c=(start)<-[:SEGMENT_ROMANIA*0..]-(pt1:Point_ROMANIA)<-[:CONNECTED_ROMANIA]-(e:Establishment_ROMANIA)
WITH 2 * 6371 * asin(sqrt(haversin(radians(toFloat(e.Y) - toFloat(start.Y))) + cos(radians(toFloat(e.Y)))* cos(radians(toFloat(start.Y)))* haversin(radians(toFloat(e.X) - toFloat(start.X))))) AS distance, e, c
WHERE distance <= 5000
WITH Distinct e, filter(n in rels(c) where n.ORIGIN_POLYLINE IS NOT NULL) AS segments, distance
RETURN e as nodes, extract(n in segments | n.ORIGIN_POLYLINE) as polylines, distance
