Elasticsearch遍歷嵌套對象中的范圍查詢結果
[英]Elasticsearch iterate over range query result in nested object
問題描述
我有一個elasticsearch索引，其中有一個嵌套的對象，稱為availability，其中有一個日期和一個布爾字段，映射模式如下
{
"hotel_nested" : {
"mappings" : {
"doc" : {
"properties" : {
"amenities" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"availability" : {
"type" : "nested",
"properties" : {
"date" : {
"type" : "date",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
},
"format" : "MM/dd/yyyy HH:mm:ss||MM/dd/yyyy||epoch_millis"
},
"status" : {
"type" : "boolean"
}
}
},
"dailyRate" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"destination" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"hotelName" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"location" : {
"properties" : {
"lat" : {
"type" : "float"
},
"lon" : {
"type" : "float"
}
}
},
"maxOccupancy" : {
"type" : "long"
},
"propertyType" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"roomType" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"starRating" : {
"type" : "float"
}
}
}
}
}
}

我的問題是，我想在兩個日期之間進行搜索，以查明兩個日期之間所有日期的酒店空房狀態是否為真，並且在粗略水平上也與城市名稱匹配，我還有其他搜索條件，我認為我可以處理，但是找到兩個日期之間所有日期的真實狀態困擾着我
例如，搜索查詢參數城市Albuquerque，開始日期10/22/2017和結束日期10/24/2017
我創建了一個查詢，該查詢給出了不想要的結果，我的查詢是
{
"query": {
"bool": {
"must":[
{
"match": {
"destination": {
"query": "Albuquerque" ,
"operator": "and"
}
}
}
],
"filter": {
"bool": {
"must": [ {
"nested": {
"path": "availability",
"query": {
"bool": {
"must": [
{
"range": {
"availability.date":{ "gte": "10/22/2017",
"lte":"10/24/2017"}
}
},
{
"term": {
"availability.status": "true"
}
}
]
}
}
}
}
]
}
}
}
}
}
該查詢的第一個匹配項是

在日期10/23/2017和10/24/2017的此命中狀態為false有人可以指導我正確的方向，或者可以提供示例搜索查詢來解決此問題

您需要將嵌套查詢放在must子句下。 在嵌套查詢的底部添加inner_hits鍵，並在頭部啟用特定的_source字段（因為我們不在乎與嵌套查詢不匹配的其余子文檔），如下所示：
{
"_source": [
"hotelName",
"dailyRate"
],
"query": {
"bool": {
"must": [
{
"match": {
"destination": {
"query": "Albuquerque",
"operator": "and"
}
}
},
{
"nested": {
"path": "availability",
"query": {
"bool": {
"must": [
{
"range": {
"availability.date": {
"gte": "10/22/2017",
"lte": "10/24/2017"
}
}
},
{
"term": {
"availability.status": "true"
}
}
]
}
},
"inner_hits": {
"size": 10
}
}
}
]
}
}
}
請注意，現在您將僅獲得符合條件的嵌套文檔，例如，對於您的示例，結果將是：
{
"_index": "hotel_nested",
"_type": "doc",
"_id": "305",
"_score": 4.815987,
"_source": {
"hotelName": "Sheraton San Diego Hotel & Marina",
"dailyRate": "$462.59"
},
"inner_hits": {
"availability": {
"hits": {
"total": 1,
"hits": [
{
"date": "10/22/2017",
"status": true
}
]
}
}
}
}
因此，現在，您必須檢查10月22-24范圍內的所有日期是否都存在。
一種快捷方式是標記"inner_hits":{"size":0}然后查看結果並檢查inner_hits的數量inner_hits等於10月22-24天內的天數：
"inner_hits"."availability"."hits"."total" == 3
MySQL 獲取日期范圍錯誤結果 - 查詢忽略指定范圍
[英]MySQL Date range incorrect result obtained - Query ignores the specified range
