If we have a node related with other nodes by the same type of relationship

classmetadata<-INSTANCE_OF-instance(TheNodeINeed)-RELATED_TO->...................

 - ->listype(The owner(name=d,etc))
 - ->listype(The state(name=x,etc))
 - ->listype(The propertie(name=y,etc))
 - ->listype(The location(name=z,etc))

The instance node to find, must be looking by a node classmetadata within a index by its name(this is easy) and instance name (this is easy too) and also by the listype.name=.. and listype.name=.. and listype.name=.. and here is the problem:

If I try looking just for the instance with name MyInstance who is RELATED_TO a owner with name d, here I only quering about one listype node there’s no problem, this query works

START classmetadata = node:classes(name = "MyClassMetadata")
MATCH classmetadata<-[:INSTANCE_OF]-instance-[:RELATED_TO]->listype
WHERE instance.name="MyInstance" and listype.name = "d"
RETURN instance, listype
ORDER BY instance.name ASC skip 0 limit 10

but if I need to look for the instance with name MyInstance who is RELATED_TO a owner with name d and is also RELATED to state with name x and is also RELATED to propertie with name y there is a problem the query result is always empty, is there any way to filter about two o three or more nodes.properties(listype.name) at same time if they are related by the same type of relatioship?

something like this is not working

START classmetadata = node:classes(name = "MyClassMetadata")
MATCH classmetadata<-[:INSTANCE_OF]-instance-[:RELATED_TO]->listype
WHERE instance.name = "MyInstance" AND listype.name = "x"
AND listype.name = "y" AND listype.name="d" RETURN instance, listype
ORDER BY instance.name ASC skip 0 limit 10

    I added the name property to each relationship in order to be sure that I am making the filtering in the right node.

    START classmetadata = node:classes(name = "MyClassMetadata")
MATCH classmetadata<-[:INSTANCE_OF]-instance-[r1:RELATED_TO]->listype1,
instance-[r2:RELATED_TO]->listype2, 
instance-[r3:RELATED_TO]->listype3 

WHERE instance.name = "MyInstance" AND 
r1.name="state" AND listype1.name = "x" AND 
r2.name="property" AND listype2.name = "y" AND 
r3.name="owner" AND listype3.name="d" 
RETURN instance, listype
ORDER BY instance.name ASC skip 0 limit 10
