如何在Elasticsearch中使用JavaClient实施“建议”查询

Question

I want to execute the following query with JavaClient.

{
    "suggest": {
        "my-suggestion-1": {
            "text": "sample",
            "completion": {
                "field": "suggest1",
                "size": 10
            }
        }
    }
}

I could not find the document.

Please let me know the URL of the document. Also, how should I implement it?

Someone, please lend me your wisdom.

Answer 1

Try something like

TermSuggestionBuilder termSuggestionBuilder = SuggestBuilders.termSuggestion("field_name").text("my suggest terms");
client.prepareSearch("my_index").setSize(0).suggest(new SuggestBuilder().addSuggestion("foo", termSuggestionBuilder)).get();

A good thing to do is usually to check the Elasticsearch tests itself, like the CompletionSuggestSearchIT
