Let's say we have a mixed set of nodes that represent different types. All
of these nodes have multiple properties. Some of these properties are
arrays with ids of these types.
node1.foonames = ["name1", "othername1",...]
node1.ids = ["id1","yetanotherid1", ...]
node2.barnames = ["name2"]
node2.ids = ["id2","otherid2","yetanotherid2"]
I would like to be able to universally query all the names and ids.
(Imaging the names and ids come from different sources)
Before 2.x I would just push all the names and ids in an
index.forNodes("idindex").add(node1,"id",...). Then I could just use that
index in cypher (START n=node:idindex(id={'name2'}) ..) to get the nodes I
want.
>From what I heard and read in blogs, etc Neo4j wants to phase out this
functionality eventually.
So in a Label-world I would make something like:
create index on :Indexed(indexed)
node1.label = Indexed
node1.indexed =["name1", "othername1",...,"id1","yetanotherid1", ...]
node1.ids =["id1","yetanotherid1", ...]
node1.names=["name1", "othername1",...]
// same for node2
and then query in cypher:
match (n:Indexed) where "name1" in n.indexed return n
So my questions are:
1. Can I make an index that encompasses multiple properties but behaves as
if it was just one?
2. does the index actually help me in the where "name1" in n.indexed case?
3. any alternative ideas? Or is legacy indexing still cool and I do not
have to feel ashamed of it? :)
