Hello, I'm VERY new to ES and I mainly use C# so I downloaded the NEST .net API. I indexed an object (named "Nation" -\> ES type "Nations") which has the following properties for example: Name, ISO. When I look at the \_source in ES I see it turned all my properties to lowercase: name. iSO. So I read a bit on NEST and saw they have an attribute for the property: - [ElasticProperty(Name = "Name")] public stirng Name { get; set; } - [ElasticProperty(Name = "ISO")] public stirng ISO { get; set; } But this is annoying since it's on the prop level, so I have to set it for all the hundreds of props I have in the project. Isn't there an easier way to tel ES to stop lower-casing my fields? Thanks. Liron -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi Liron, Nests default behavior is to camelCase all the property names, you can easily override this globally by setting a custom TypeNameInferrer method. var uri = new Uri("[http://localhost:9200](http://localhost:9200)"); var settings = new ConnectionSettings(uri) .SetDefaultIndex("mydefaultindex") _.SetTypeNameInferrer(i=\>i);_ var client = new ElasticClient(settings); This leaves the original propertynames untouched. Be aware though that an explicit ElasticProperty Annotation always takes precedence so remove the annotations.

Thanks. But I meant the properties' names. no the object (/type) name. The correct syntax is: .SetDefaultTypeNameInferrer(p =\> p.Name); So .net' Location object turn into Location Type in ES. Any thought as to how to make something similar for properties? Thanks again, Liron -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Argh, serves me right for writing code from the top of my head before the first cuppa. See: [How to disable camelCase ? · Issue #275 · elastic/elasticsearch-net · GitHub](https://github.com/Mpdreamz/NEST/issues/275) I'll be sure to improve the API for this in the next version!

Ohh... You're a life saver. I almost gave up on this... Perfect. So just to keep it all in this thread, here is the final solution: var settings = new ConnectionSettings(new Uri("localhost/9200")); settings .SetDefaultTypeNameInferrer(p =\> p.Name); var client = new ElasticClient(settings); client.ModifyJsonSerializationSettings(s =\> s.ContractResolver = new Nest.Resolvers.ElasticResolver(settings); ); Thanks. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
