Support analysis aliases

[micah-bloomerang]

I'm trying to convert an existing code base to Nest, and I'm having trouble with the CreateIndex command. The command I'm trying to convert is this:

{ 
  "index": {
    "analysis": {
      "analyzer": {
        "default": {
          "type": "custom",
          "tokenizer": "uax_url_email",
          "filter": ["standard", "asciifolding", "lowercase", "stop"],
          "alias": ["default_index", "default_search"]
        }
      }
    }
  }
}

I think I want something that looks like:

client.CreateIndex(indexName, c => c
                .Analysis(a => a
                    .Analyzers(a2 => a2
                        .Add("default", new CustomAnalyzer() {
                            Tokenizer = "uax_url_email",
                            Filter = new List<string>() { "standard", "asciifolding", "lowercase", "stop" },
                            Alias = new List<string>() { "default_index", "default_search" }
                        }))));

but Alias isn't available on CustomAnalyzer. What's the best way to pull this off?

From what I can tell at http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-analyzers.html, the default customer analyzer affects both indexing and search; default_index and default_search only affect one or the other. If I'm setting the default analyzer, I shouldn't need to set default_index and default_search also. Maybe someone who knows more about ElasticSearch than I do can confirm?

You are right that in your case you do not need the aliasing to make it the default on index and search time.

Reopening this because you should be able to set the alias as you specified.
