Hi Boban, aside from using an indexing service to grab certain information from neo4j (as Paddy mentioned correctly) you certainly should get yourself learning about traversal concepts.Traversing does not mean just iterating over "elements over a single node" but traversing the whole graph (if you want to) : hence the naming "traverse". So, from the way you ask about stuff in you mail, i think its worth understand that unique concept of graph database. Directly falling back to the index service does not really embrace why you are a graph db at all. As a starter, looking at the javadoc of Node.traverse or its neo4j 1.1.0-SNAPSHOT successor TraversalDescription and friends helps a lot already.
If you cannot succeed that way, read for common misconceptions like that one [1] Also try to adopt some design best practices when creating the graph [2] cheers, Toni [1] http://wiki.neo4j.org/content/Neo_Mistakes#Unbalanced_graph [2] http://wiki.neo4j.org/content/Design_Guide On Mon, Jul 5, 2010 at 4:19 PM, Boban Erakovic <[email protected]> wrote: > Greetings, I have some misunderstanding about neo4j. > Once, when I store some nodes and relations into database, how can I query > it? > So I store information 5 days ago, and now I want to query?
