我有一个有效的过滤弹性搜索查询,但我想使用minimum_should_match来指示ES只返回至少有3个匹配的结果。但我似乎无法弄清楚minimum_should_match的位置。我应该把它放在哪里?
{
"size": 100,
"sort": {
"price_monthly": "asc"
},
"query": {
"filtered": {
"query": {
"match_all": []
},
"filter": {
"bool": {
"must": [],
"should": [
[
{
"range": {
"mb.untouched": {
"gte": "0",
"lt": "500"
}
}
},
{
"range": {
"mb.untouched": {
"gte": "500",
"lt": "1000"
}
}
}
],
[
{
"range": {
"minutes.untouched": {
"gte": "0",
"lt": "100"
}
}
},
{
"range": {
"minutes.untouched": {
"gte": "200",
"lt": "300"
}
}
}
],
[
{
"range": {
"sms.untouched": {
"gte": "750",
"lt": "1000"
}
}
}
]
],
"must_not": {
"missing": {

}
}

}
},
"prolong.untouched": {
"terms": {
"field": "prolong.untouched"
}
},
"duration.untouched": {
"terms": {
"field": "duration.untouched"
}
},
"mb.untouched": {
"histogram": {
"field": "mb.untouched",
"interval": 500,
"min_doc_count": 1
}
},
"sms.untouched": {
"histogram": {
"field": "sms.untouched",
"interval": 250,
"min_doc_count": 1
}
},
"minutes.untouched": {
"histogram": {
"field": "minutes.untouched",
"interval": 100,
"min_doc_count": 1
}
},
"price_monthly.untouched": {
"histogram": {
"field": "price_monthly.untouched",
"interval": 5,
"min_doc_count": 1
}
}
}
}

为了使用minimum_should_match
,您需要稍微重写过滤后的查询,即您需要将should
子句移动到已过滤查询的query
部分,将must_not
保留在filter
部分(因为missing
是一个过滤器)。然后,您可以在minimum_should_match: 3
查询部分添加bool
,如下所示:
{
"size": 100,
"sort": {
"price_monthly": "asc"
},
"query": {
"filtered": {
"query": {
"bool": {
"minimum_should_match": 3,
"must": [],
"should": [
[
{
"range": {
"mb.untouched": {
"gte": "0",
"lt": "500"
}
}
},
{
"range": {
"mb.untouched": {
"gte": "500",
"lt": "1000"
}
}
}
],
[
{
"range": {
"minutes.untouched": {
"gte": "0",
"lt": "100"
}
}
},
{
"range": {
"minutes.untouched": {
"gte": "200",
"lt": "300"
}
}
}
],
[
{
"range": {
"sms.untouched": {
"gte": "750",
"lt": "1000"
}
}
}
]
]
}
},
"filter": {
"bool": {
"must_not": {
"missing": {
"field": "provider.untouched"
}
}
}
},
"strategy": "query_first"
}
},
"aggs": {
"provider.untouched": {
"terms": {
"field": "provider.untouched"
}
},
"prolong.untouched": {
"terms": {
"field": "prolong.untouched"
}
},
"duration.untouched": {
"terms": {
"field": "duration.untouched"
}
},
"mb.untouched": {
"histogram": {
"field": "mb.untouched",

"min_doc_count": 1
}
},
"sms.untouched": {

"field": "sms.untouched",

"min_doc_count": 1
}
},
"minutes.untouched": {
