OrientDB

Im using OrientDB type graph. I need syntax of Gremlin for search same SQL LIKE operator LIKE 'search%' or LIKE '%search%' I've check with has and filter (in http://gremlindocs.com/ ). However it's must determine exact value is passed with type property. I think this is incorrect with logic of search. Thanks for anything. Daniel Kuppitz Try: g.V().filter({ it.getProperty("foo").startsWith("search") }) or g.V().filter({ it.getProperty("foo").contains("search") }) You can use filter with a bit of regex: gremlin> g = TinkerGraphFactory.createTinkerGraph() ==>tinkergraph[vertices:6 edges:6]

Are there any implementations, api or examples of OrientDB and C#. The reason I am looking at OrientDB is becuase it's the only one that I found that is a combination of Graph and Document. Any suggestions on how I should try this. My next choice is RavenDB, but I am not sure if it supports joins or linked documents? Any thoughts... I just developed a first version of a REST client for OrientDB. http://netorientdb.codeplex.com Roman Gordon OrientDB has an official binary driver for .NET look here http://orientdb.com/docs/3.0.x/ Example of usage OrientDB-NET.binary string release = OClient

How can two joinFieldNames be specified? This is the scripted(post processing) version: Create edge Expands from (select from MC where sample=1 and mkey=6) to (select from Event where sample=1 and mcl=6) . This works, but is not suitable for production. Can anyone help? 回答1: you can simply add 2 joinFieldName(s) like { "edge": { "class": "Conn", "joinFieldName": "b1", "lookup": "A.a1", "joinFieldName":

I've noticed that currently the DBMS supports the previous version (2.x) of the Tinkerpop traversal language which, for example, only allows to directly filter edges by label, but not vertices :( . I was quite satisfied with gremlin-scala and orientDB-gremlin but I found that not all my queries where efficiently executed (some indexes were ignored). Is there any other way? Thanks in advance :) 回答1: Orientdb-gremlin is indeed the only available driver, and while it works
