使用NEST为_all字段设置分析器 [英] Set analyzers for _all field with NEST

问题描述

如

_all字段允许设置存储，term_vector和分析器(具有特定的index_analyzer和search_analyzer).

The _all fields allows for store, term_vector and analyzer (with specific index_analyzer and search_analyzer) to be set.

是否可以在_all字段上为使用NEST的映射指定index_analyzer和search_analyzer属性?具体来说，我希望能够为索引设置以下内容:

Is there a way to specify the index_analyzer and search_analyzer attributes on the _all field for a mapping with NEST? Specifically, I would like to be able to set the following for my index:

 {
     "model": {
        "_all": { 
             "index_analyzer": "nGram_analyzer",
             "search_analyzer": "whitespace_analyzer"
        }

       ...
  }

在Fluent Mapping中，我看不到任何可以做到这一点的东西.如果不通过Fluent Mapping可以手动设置吗?

I did not see anything that would allow for this in the Fluent Mappings. Can I set this manually if not via Fluent Mapping?

推荐答案

从NEST 1.0开始，您现在可以执行以下操作:

Starting from NEST 1.0 you can now do this:

var result = this._client.Map<ElasticsearchProject>(m => m
    .AllField(a=>a
        .Enabled() 
        .IndexAnalyzer("nGram_analyzer")
        .SearchAnalyzer("whitespace_analyzer")
        .TermVector(TermVectorOption.with_positions_offsets)
    )
    ...
    ...
