elasticsearch - Elasticsearch 通配符查询结果命中也发生变化

Question

Elasticsearch 版本：7.10.2 目前，我在新版本中遇到了一个关于通配符类型的通配符查询的奇怪问题。我使用 DSL 查询如下

{"_source":"brand_name","query":{"wildcard":{"brand_name":{"value":"*wUg*"}}},"sort":[{"shop_id":{"order":"desc"}}]}

命中结果响应 在此处输入图像描述 在此处 输入图像描述

但是相同的查询总命中数总是每次都在变化，我阅读了官方文档并没有找到任何答案。那么有没有高手可以帮忙检查一下这个问题？索引设置

  "wildcard_query_1000w" : {
    "settings" : {
      "index" : {
        "routing" : {

            "include" : {
              "_tier_preference" : "data_content"
