[Neo4j] REST Traversal docs

2011-06-21 Thread Josh Adell
I've been googling and searching all over the nei4j site and wiki for examples of doing traversal through the REST API. I know I'll be writing my traversal functions in Javascript. Are there docs on the APIs of the objects I'll have access to in my prune evaluator and return functions? Thanks, J

I'd guess not. Feel free to try upgrading the lucene version and see what happens. I dug around and I think these commits will fix the source code incompatibilities when moving from lucene 3.0.1 to 3.1.0: https://github.com/neo4j/community/commit/931bdb49d2017e11440bf588bc170a68f09a83b2 https://gi

Re: [Neo4j] Scala/Lift as neo4j frontend

2011-06-21 Thread Andreas Kollegger
Hi Manav, Embedding Neo4j in a Scala/Lift application is a perfectly sensible thing to do. The biggest trade-off is missing the web-based administration for the database. Are you thinking about using the Lift as the user application, or just as an alternative for exposing domain-specific interf

2011-06-21 Thread Mattias Persson
I'm afraid it's too late to switch to a new version of lucene now for 1.4, but I can see it entering early 1.5 if there's no show stopper. Compilation-and-unit-tests-wise Lucene 3.2 seems to just work when replacing it with 3.1 in 1.4-SNAPSHOT, that's all I know about it at this stage. I also don't

Hi Sorry for the late reply. I have done some experiment trying to run neo4j.rb on MRI a while a ago, check this old branch: https://github.com/andreasronge/neo4j/tree/rjb It might be possible to run neo4j.rb on MRI but some parts of the code has to be rewritten specifically for RJB. I would be r
