laravel - 在Elasticsearch中进行自定义排序？

Question

如何进行这样的排序:

->orderByRaw('payed_promo >= ' . $time . ' DESC') 
->orderByRaw('payed_vip >= ' . $time . ' DESC') 
->orderBy('rating->urls->' . $url_1 . '->rating', 'DESC')

这是我从MySQL(Eloquent laravel)排序的方法，如何在Elasticsearch上做到这一点？

Answer 1

您可以指定“sort”参数。

在官方文档中，“显示所有匹配的结果，先按日期排序，然后按相关性排序”:

   "sort": [
        { "date":   { "order": "desc" }},
        { "_score": { "order": "desc" }}
    ]

还有一个“boost”参数，它会影响默认结果顺序:
