Elasticsearch - Implement Completion Suggestion in Java (API Version 5!)

Question

I am trying to implement a completion suggestion for my java application. I've read the documentation but could not find anything on how to implement it using the Java API in Version 5.0.1. (All i found was related to older versions)

this.client.prepareSuggest...

=> does not exist anymore

this.client.prepareSearch... .addSuggestion(csb);

=> does not accept CompletionSuggestionBuilder

This is my maven dependency:

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>transport</artifactId>
    <version>5.0.1</version>
</dependency>

Can anyone provide an example?

The correct way of doing it is like this:

CompletionSuggestionBuilder csb = SuggestBuilders.completionSuggestion("foo")
    .prefix("prefix");
client().prepareSearch()
    .suggest(new SuggestBuilder().addSuggestion("foo", csb))

Could you also help me on how to specify fuzziness ? I cannot find a setter for that in CompletionSuggestionBuilder => elastic.co/guide/en/elasticsearch/reference/current/…

You can use the overloaded prefix(String, Fuzziness) method for that purpose

@Gibbs you can definitely use the low level RETS client and send your DSL queries.

the high-level client uses the low-level client, so it should be quicker, but you won't really notice a thing.
