我认为您可以摆脱排序通过 top_hits 中的两个字段：通过活动和通过已收集。基本上，您希望 true 首先出现且相等时，然后按 collected 进行排序。诸如此类的内容始终会显示 active：true 文档，该文档按收集的排序。

I think you can get away with sorting by two fields in your top_hits: by active and by collected. Basically, you want trues to be first and when equal, then sort by collected. Something like the following will always show the active:true documents sorted by collected.

此解决方案的唯一缺点是，如果您没有任何活动文档，则 top_hits 将显示一个活动文档：错误的文档。

The only downside to this solution is that if you don't have any active documents, top_hits will show one active:false document.
