Setting analyzer from plugin in ElasticSearch with NEST -

my first post ! i'm trying set stempel analyzer (es analyzer polish language) string field. can through put request:

{    "doc": {       "_source": {          "enabled": false       },       "properties": {          "file": {             "type": "attachment",             **"analyzer": "polish"**,             "fields": {                "content": {                   "type": "string",                   "term_vector": "with_positions_offsets"                }             }          }       }    } } 

and works fine. trying same thing through nest.

 [elasticproperty(name = "_content", termvector = termvectoroption.withpositionsoffsets, analyzer = "polish")]  public string content { get; set; } 

is not working neither do:

            client.createindex(index, b => b.addmapping<docines>(m => m             .mapfromattributes()             .properties(props => props                 .string(s => s                     .name(p => p.file.content)                     .analyzer("polish")                      )))); 

when i'm using

var result = client.analyze(a => a.index("doc").analyzer("polish").text("...text...")); 

it works fine, .net detecting analyzer. i'm using es 2.1.1. & nest 1.7.1

edit: inspected seems nest not doing mapping of attributes of attachment class created in .net. map attributes of document class

[elastictype(name = "docines")] public class docines {     public int institutionid { get; set;}     public int documentid { get; set; }     [elasticproperty(store = true, analyzer = "polish")]     public string title { get; set; }      [elasticproperty(type = fieldtype.attachment)]     public attachment file { get; set; }  } 

but not attachment class:

public class attachment {     [elasticproperty(name = "content2", store = true)]     public string content { get; set; }      [elasticproperty(name = "content_type2")]     public string contenttype { get; set; }      [elasticproperty(name = "name2", analyzer = "english")]     public string name { get; set; } } 

you should check compatibility matrix on github.

nest 1.7.1 not compatible es 2.1.1
