hop of those help? Neo4j does not really support indexes on relationship properties. For this reason you should consider storing the time as a property on a node. You can then use an index supported range query:
code :
MATCH (u:User)-[:INITIATED]->(e:Event)-[:PICK_UP]->(g:Grid)
WHERE e.time > 1600 AND e.time < 2000
RETURN u.name;

should help you out Beginner Cypher question. I know how to get all the nodes of a particular type attached to a particular person in my database. Here I am retrieving all the friends of a particular person, within 10 hops: , You can filter on the label of the friends identifier :
code :
MATCH (rebecca:Person {name:"Rebecca"})-[r*1..10]->(other)
WHERE ALL( x IN ["Friend","Neighbour"] WHERE x IN labels(other) )
RETURN rebecca, other

I hope this helps you . We have a Neo4j knowledge base article on performing match intersection that provides a few approaches to getting the result you want.
(Also keep in mind that node variables should probably be kept singular, as they will only match to a single node per row. Try to reserve plural variables to lists, to avoid confusion in your queries.)
code :
MATCH (q:Query {summary: "Looking for Japan GDP"})-[:FILTERED_BY]->(filter)
WITH filter, size((q)-[:FILTERED_BY]->()) as totalFilterCount
MATCH (r:Record)-[:GROUPED_BY]->(filter)
WITH r, count(filter) as matchedFilterCount, totalFilterCount
WHERE matchedFilterCount = totalFilterCount
RETURN r

this will help , This should work:
code :
MATCH (n:Item {name: 'A'})-[r1]-(n2:Item)
WITH n, COLLECT(r1) AS rs, COLLECT(n2) as others
UNWIND others AS n2
OPTIONAL MATCH (n2)-[r2]-(x)
WHERE x IN others
RETURN n, others, rs + COLLECT(r2) AS rs
