Cypher Confusion

[betseyb]

I figured out my problems with batch inserting. 

My nodes all have properties Name and Type.  My Relationships all have types.  What I want to do is to be able to find the node(s) with the Name "foo".

From there, I might get all of the nodes that have relationships to "foo", along with their relationships, or add a new relationship between "foo" and another node, or some other task.

I turned on auto indexing on both Name and Type, but can't figure out how to query against it using cypher.  I'm going to be doing all of this via the REST API, but for now I'm using the web console to debug my cypher queries.  Your help is greatly appreciated!

START me = node:node_auto_index(name="max")

RETURN me

Thanks.  I tried that, and I get the error "Index 'node_auto_index' does not exist.  The auto-index is on in my neo4j.properties file, do I need to include it in the batch properties as well?

I'm finding this all quite overwhelming.

Hi there,
look at the following code that I just added to the tests in order to
demonstrate the behavior: The Batchinserter has no knowledge of
autoindexing, but you can just create the index with the name
node_auto_index and it will be reused in your configured normal
instance:

Does that work for you?

And,
it is now part of the code base at
https://github.com/neo4j/community/blob/b59e0ef0a3ece6f6e761cc8229c1ae83a8d7d340/lucene-index/src/test/java/org/neo4j/unsafe/batchinsert/TestLuceneBatchInsert.java#L318

so you can compile it yourself.
