在Elasticsearch'中编写查询；s的Java客户端

我使用了弹性搜索java客户端， 我正在实现一个搜索应用程序。 （索引已经建立）

我想重现弹性搜索java客户端，如下查询

但是，它无法复制

如果您熟悉java客户端， 我要你告诉我

我要执行的查询（示例字段有java和php） 在java客户机上组装查询 ↑ “builder”变量的输出内容 输出时，match中包含额外的属性。 此外，我还不知道如何匹配多个单词

有人，请把你的智慧借给我

环境

• 语言：Java8
• 框架：Spring
• Elasticsearch客户端（jar）版本
  *Org.elasticsearch:5.1.1
  *Org.elasticsearch.client:5.1.1
• Elasticsearch版本：5.3.1

假设我有以下映射：

{
    "articles": {
        "mappings": {
            "article": {
                "properties": {
                    "sample": {
                        "type": "text"
                    }
                }
            }
        }
    }
}

我索引了以下三份文件：

{ "sample" : "java php" },
{ "sample" : "java" },
{ "sample" : "php" }

您提供的es查询提供了以下结果：

{
    "took": 1,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "failed": 0
    },
    "hits": {
        "total": 1,
        "max_score": 0.51623213,
        "hits": [
            {
                "_index": "articles",
                "_type": "article",
                "_id": "AV0rSbyjpRVEWsG0iTxj",
                "_score": 0.51623213,
                "_source": {
                    "sample": "java php"
                }
            }
        ]
    }
}

为了获得与Java API相同的结果，我使用：

BoolQueryBuilder boolQuery = QueryBuilders.boolQuery()
        .must(QueryBuilders.matchQuery ("sample", "java"))
        .must(QueryBuilders.matchQuery ("sample", "php"));
SearchRequestBuilder builder = client.prepareSearch()
        .setSize(50)
        .setQuery(boolQuery);

SearchResponse response;
try {
    response = builder.execute().get();

    for (SearchHit hit : response.getHits().getHits()) {
        LOG.info("Result: " + hit.getSourceAsString());
    }
} catch (InterruptedException | ExecutionException e) {
    // handle exception
    LOG.error("Exception while executing query {}", e);
}

结果:

Result: { "sample" : "java php" }

调试时在查询中看到的所有附加属性都只是默认值，Java API会显式设置它们。

谢谢！我非常感激。我能够成功地实施。

{
    "took": 1,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "failed": 0
    },
    "hits": {
        "total": 1,
        "max_score": 0.51623213,
        "hits": [
            {
                "_index": "articles",
                "_type": "article",
                "_id": "AV0rSbyjpRVEWsG0iTxj",
                "_score": 0.51623213,
                "_source": {
                    "sample": "java php"
                }
            }
        ]
    }
}

BoolQueryBuilder boolQuery = QueryBuilders.boolQuery()
        .must(QueryBuilders.matchQuery ("sample", "java"))
        .must(QueryBuilders.matchQuery ("sample", "php"));
SearchRequestBuilder builder = client.prepareSearch()
        .setSize(50)
        .setQuery(boolQuery);

SearchResponse response;
try {
    response = builder.execute().get();

    for (SearchHit hit : response.getHits().getHits()) {
        LOG.info("Result: " + hit.getSourceAsString());
    }
} catch (InterruptedException | ExecutionException e) {
    // handle exception
    LOG.error("Exception while executing query {}", e);
}

Result: { "sample" : "java php" }
