Question

我是Elastic Search API的新手。我有一个要求，我需要查询和列出强制包含以下属性的文件，比如说

＆＃34;请求：＆＃34; / v3？id = 100000＆＃34; ＆安培; ＆＃34;输入：＆＃34; GET＆＃34;

结果应包含包含上述内容的文档列表。我尝试了以下内容，它可以获得上述任何一项。

{
    "query": {
        "match": {
               "type": "GET"
           }
    }
}

我试过

{
    "query": {
        "match": {
               "type": "GET",
               "request: "/v3/id=100000"
           }
    }
}

失败了......

有人可以建议我查询列出具有上述属性的所有文档吗？不确定如何使用过滤器，如果我尝试显示失败 - 解析异常。

我的示例文档：

{
  "_index": "logstash-2016.04.22",
  "_type": "endpoint-access",
  "_id": "fAhTQkDRQTiHKlzuleNA",
  "_score": null,
  "_source": {
    "@version": "1",
    "@timestamp": "2016-04-22T15:26:35.153Z",
    "offset": "43714176",
    "ident": "-",
    "auth": "-",
    "timestamp": "22/Apr/2016:15:26:35 +0000",
    "type": "GET",
    "request": "/v3?id=1b32e833-b521",
    "httpversion": "1.1",
    "response": "500",
    "bytes": "265",
    "referrer": "-",
    "agent": "-",
    "x_forwarded_for": "\"101.2.123.24\""
    "host": "101.123.115.167"
  },
  "sort": [
    1461338795153,
    1461338795153
  ]
}

您可以使用“必须”来获得结果：

public void test() {
    // creates a list of fruits
    List<Fruit> fruits = Arrays.asList(
            new Fruit("Apple", 10),
            new Fruit("Apple", 14),
            new Fruit("Pear", 4));
    // Old style.
    // holds the largest apple so far
    Fruit largeApple = null;
    for (Fruit fruit : fruits) {
        if (fruit.getType().equals("Apple")) {
            if (largeApple == null
                    || largeApple.size() < fruit.size()) {
                largeApple = fruit;
            }
        }
    }
    System.out.println("Old: " + largeApple);
    // New Style.
    Optional<Fruit> max = fruits.stream()
            .filter(f -> f.type.equals("Apple"))
            .max(Comparator.comparing(f -> f.size));
    System.out.println("Lambda: " + max);

}
