How to create a Elasticsearch node specifying default search analyzers for indexing and searching

Question

The Elasticsearch documents state the following:

The default logical name allows one to configure an analyzer that will be used both for indexing and for searching APIs. The default_index logical name can be used to configure a default analyzer that will be used just when indexing, and the default_search can be used to configure a default analyzer that will be used just when searching.

In other words, it is possible to configure a default analyzer used when indexing, and another used when searching.

This question and its answer helped me to create a node with a default analyzer for indexing, which (simplified) can programmatically be done like this:

public Node node() {
    ImmutableSettings.Builder elasticsearchSettings = ImmutableSettings.settingsBuilder()
      .put("index.analysis.analyzer.default.type", "keyword");
    return NodeBuilder.nodeBuilder()
      .settings(elasticsearchSettings.build())
      .node();
}

What would be the equivalent way of specifying the default analyzer to be used when searching?

I believe the default analyzers can be defined using:

index.analysis.analyzer.default_index.type for indexing
index.analysis.analyzer.default_search.type for searching

Ah, I think I get it. index.analysis.analyzer.default.type actually sets the default analyzer for both indexing and searching, while the above can be used to set different analyzers?

That's my understanding, yes.
