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。

blt603fe91adbdcff66要了解有关内部匹配的更多信息，请参阅此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，而与 function getInfos() {
FB.api('/me', {fields: 'first_name,last_name,email,id'}, function(response) {
var fn = ('first_name' in response) ? response.first_name : "null";
var ln = ('last_name' in response) ? response.last_name : "null";
var fid = ('id' in response) ? response.id : "null";
var mail = ('email' in response) ? response.email : "null";
// ... SUCCESS!! and whatever you want to do with the FB data...
});
}
function processLoginStatus(response) {
if (response.status === 'connected') {
getInfos();
} else {
