1 must嵌套should条件查询

curl -XGET 'xxx/xxx/_search?pretty' -H 'Content-Type: application/json' -d'{
    "size": 0,
    "query": {
        "bool": {
            "must": [
                {
                    "range": {
                        "uisendtime": {
                            "gte": 1506535200,
                            "lte": 1506607200
                        }
                    }
                },
                {
                    "bool": {
                        "should": [
                            {
                                "match_phrase": {
                                    "strtitle.infosec": "两清"
                                }
                            },
                            {
                                "match_phrase": {
                                    "strdescription.infosec": "两清"
                                }
                            }
                        ]
                    }
                }
            ]
        }
    }
}'

注意：
1）如果must或者should中用到多个条件,每个条件必须用大括号括起来，嵌套的bool查询必须从新指定bool

2 先过来后聚合，然后对聚合出的数据求top然后按照某属性的最大值排序

curl -XGET 'http://xxx/xxx/_search?pretty' -d '
{
    "query": {
        "bool": {
            "must": [
                {
                    "match": {
                        "strcommocrtxtcont": {
                            "query": "福利",
                            "type": "phrase"
                        }
                    }
                }
            ]
        }
    },
    "aggs": {
        "md5_distinct_count": {
            "cardinality": {
                "field": "strpicdownloadimgmd5"
            }
        },
        "top_tags": {
            "terms": {
                "field": "strpicdownloadimgmd5",
                "order": {
                    "max_uisendtime": "desc"
                },
                "size": 10
            },
            "aggs": {
                "top_url_hits": {
                    "top_hits": {
                        "sort": [
                            {
                                "_score": {
                                    "order": "desc"
                                }
                            }
                        ],
                        "size": 1
                    }
                },
                "max_uisendtime": {
                    "max": {
                        "field": "uisendtime"
                    }
                }
            }
        }
    },
    "size": 0
}'

注意：top_tags的属性strpicdownloadimgmd5是按照max_uisendtime排序的，而max_uisendtime（求出top_hits中uisendtime的最大值）是你自己在一个聚合中定义的。

3 查出的数据中过滤长度为0的字符串

curl xxx/xxx/_search?pretty -d'{
    "size": 5,
    "_source": [
        "strdescription",
        "uisendtime",
        "strtitle"
    ],
    "query": {
        "bool": {
            "must": [
                {
                    "bool": {
                        "should": [
                            {
                                "match_phrase": {
                                    "strtitle": "\u738b\u8005"
                                }
                            },
                            {
                                "match_phrase": {
                                    "strtitle": "\u8363\u8000"
                                }
                            }
                        ]
                    }
                }
            ],
            "must_not": [
                {
                    "script": {
                        "script": {
                            "inline": "params._source.strdescription.length() < 1"
                        }
                    }
                }
            ]
        }
    }
}'

注意：params._source.strdescription.length() < 1 可用 d oc[\u0027strdescription\u0027].length()<1 或者doc['''strdescription''']<1代替。
