并向其中添加文档。这是文件 list : [{

我正在使用以下查询来获取结果GET ten2/_search
{
"query": {
"bool": {
"must": [{
"bool": {
"must_not": [{
"bool": {
"must": [{
"nested": {
"path": "publish_details",
"query": {
"term": {
"publish_details.environment": "blt603fe91adbdcff66"
}
}
}
}, {
"nested": {
"path": "publish_details",
"query": {
"term": {
"publish_details.locale": "en-us"
}
}
}
}, {
"nested": {
"path": "publish_details",
"query": {
"term": {
"publish_details.locale": "hi-in"
}
}
}
}, {
"nested": {
"path": "publish_details",
"query": {
"term": {
"publish_details.locale": "mr-in"
}
}
}
}]
}
}]
}
}
}
}
}
请帮助我查询以获得期望的结果。前两个具有相同uid的dicuemtns仅publish_details.locale是不同的。我使用must_not内的must查询来获取结果,当前我正在获取所有三个文档,但是我只想要最后一个。我有一百万个文件。

在您的映射,索引数据和搜索查询中添加一个有效的示例
搜索查询:
{
"query": {
"nested": {
"path": "publish_details",
"query": {
"bool": {
"must": [
{
"match": {
"publish_details.locale": "en-us"
}
}
],
"must_not": [
{
"match": {
"publish_details.environment": "blt603fe91adbdcff66"
}
},
{
"match": {
"publish_details.locale": "hi-in"
}
},
{
"match": {
"publish_details.locale": "mr-in"
}
}
]
}
},

要了解有关内部点击的更多信息,请引用此documentation。上面的查询仅返回第三个文档,从而满足了搜索查询的条件。在内部匹配中,仅返回第三份文档的一部分,而丢弃与
blt603fe91adbdcff66
相匹配的部分。
