我正在尝试在弹性搜索中按价格范围过滤酒店房间。房间有默认的每晚价格，也可以为特定日期设置自定义价格。
我将nightlyPrice自定义价格的嵌套对象与日期一起存储。映射是 smt。喜欢：
{
"adverts": {
"mappings": {
"advert": {
"properties": {
"nightlyPrice": {"type": "float"},
"customPrices": {
"type": "nested",
"properties": {
"date": {"type": "date"},
"price": {"type": "float"}
}
}
}
}
}
}
}
例如，我想在 7 月 1 日至 7 日期间获得价格在 100 美元和 200 美元之间的房间。
所以我想出了这个逻辑：
customPrices.date必须在 2019-07-01 和 2019-07-07之间customPrices.price以及 100 和 200 之间。- 或
nightlyPrice必须在 100 到 200 之间，并且 nocustomPrices.date设置在 7 月 5 日到 7 日之间。
但是我无法将此逻辑应用于弹性搜索，我猜嵌套对象/查询有点棘手。
这是我提出的最后一个查询：
{
"query": {
"bool": {
"filter": [
{
"term": {
"status": "active"
}
}
],
"must": [
{
"bool": {
"should": [
{
"nested": {
"path": "customPrices",
"query": {
"bool": {
"must": [
{
"range": {
"date": {
"from": "2019-07-01",
"to": "2019-07-07"
}
}
},
{
"range": {
"price": {
"from": 100,
"to": 200
}
}
}
]
}
}
}
},
{
"bool": {
"must": [
{
"range": {
"nightlyPrice": {
"from": 100,
"to": 200
}
}
}
],
"must_not": [
{
"nested": {
"path": "customPrices",
"query": {
"range": {
"customPrices.date": {
"from": "2019-07-01",
"to": "2019-07-07"
}
}
}
}
}
]
}
}
]
}
}
]
}
}
}
此查询的问题是，如果 customPrices.date 匹配日期范围，则无论价格范围如何，它都不会与文档匹配。我尝试了 1 - 100000 美元的价格范围，但仍然不匹配。
试图使用解释 API 来理解为什么特定文档不匹配但我不明白，它说user requested match_none查询但有这个should查询所以它应该匹配嵌套查询（第一个）：

"_type": "advert",
"_id": "13867",
