Re: [Neo4j] IndexProvider question

I would like to set AND as the default operator when I create index using the new index library: Index = indexProvider.nodeIndex( fulltext, LuceneIndexProvider.FULLTEXT_CONFIG );   I didn't find setDefaultOperator (similar to the one in LuceneFulltextQueryIndexService )in any of the provider

I got cali's benchmark result. Well, sort of benchmarks: http://github.com/dmitriid/cali/wiki/Benchmarks-of-sorts There's neo4j, TinkerGraph and OrientDB For some odd reason neo4j performs abysmally, though yesterday it was way, way better: http://twitter.com/dmitriid/status/23912123904 Will

Yeah, I guess that could be a problem (or the problem). Hmmm... I'll try and run the benchmark on a less busier machine and see what happens then. Thanks for the tip! FWIW, I've noticed that neo4j seems to be fairly sensitive to disk I/O performance. I couldn't get it to work at all on

Hi Dimitri, Also, Blueprints assumes auto transactions (that is, every delete/write is a committed transaction). You can turn that feature off if you want better write/delete performance. One of my next big goals with Blueprints is a general-purpose transaction model so that all

[Neo4j] Relationship Check During Traversal

2010-09-10 Thread Paddy
Hi just a quick question regarding the use of the PruneEvaluator I was wondering what would be the best way to modify the TraversalDescription in the Dijkstra algorithm in order to prune a traversal when a branch has reached a second transfer relationship. I want to avoid multiple transfers in a

Re: [Neo4j] Relationship Check During Traversal

Hi Paddy, One idea is to prune the traversal by looking at whether the path so far already has a transfer relationship or not. You would then do some kind of filtering of the resulting paths, e.g. only accepting those with correct end nodes. I don't know if the computational complexity of this is
