Elasticsearch Java API，命中分数始终为1.0

Question

I used ElasticSearch java client. I do search with query_string , and I get response, but score always be 1.0 .

code is:

    String query = "{\"query\": {\"query_string\": {\"query\": \"weblog data4\"}}}";
    SearchRequestBuilder builder = client
            .prepareSearch("flume-2016-08-10")
            .setQuery(query)
            .addHighlightedField("*")
            .setHighlighterRequireFieldMatch(false)
            .setFrom(0).setSize(60).setExplain(true);
    SearchResponse response  = builder.execute().actionGet();

    System.out.println(response.toString());
    System.out.println(response.getHits().getAt(0).getSource());
    System.out.println(response.getHits().getAt(0).getHighlightFields());
    client.close();

result is:

However, I do search in elaseticsearch-head, I get response with correct score.

So, How do I get correct score with java?

This solved my problem:

change:

String query = "{\\"query\\": {\\"query_string\\": {\\"query\\": \\"weblog data4\\"}}}";

to:

String query = "{\\"query_string\\": {\\"query\\": \\"weblog data4\\"}}";
