当我在 Elastic Search 5.2.0 中有超过 64 个聚合时，它会失败并显示：
{
"ok": false,
"message": "Unable to connect to the server."
}
此问题与 Elastic Cloud 有关 - 我在本地弹性实例上进行了测试，它没有此限制。
这是预期的行为吗？
我曾尝试删除不同的聚合，但这似乎都归结为聚合的数量。它适用于 65 个或更少的聚合。
这是简单的聚合，如下所示：
"aggs": {
"wheelSize": {
"filter": { ... },
"aggs": {
"facet_terms": {
"terms": {
"field": "facets.wheelSize",
"size": 1000
}
}
}
},
"tireSize": {
"filter": { ... },
"aggs": {
"facet_terms": {
"terms": {
"field": "facets.tireSize",
"size": 1000
}
}
}
}
}
