我想了解如何使用我的QnA Maker来识别知识库中前10个最热门或最常见的提问？QnA中有没有用于存储提问频率的参数或元数据键？Azure搜索在这里是否有帮助？请提供建议…
提前感谢！！

延续@人名的回答，假设你已经为你的机器人QnA认知服务启用了Application Insights，那么一旦你导航到分析页面（如@人名所详细说明的），你可以使用以下查询之一：
这些查询可能不是最优化的或性能最佳的，因为我只是对样本查询进行了一些修改，直到我得到了想要的结果。
// 过去48小时内的热门提问requests| where url endswith "generateAnswer" and timestamp > ago(48h) | project timestamp, id, name, resultCode, duration| parse kind = regex name with *"(?i)knowledgebases/"KbId"/generateAnswer"| join kind= inner (traces | extend id = operation_ParentId) on id| extend question = tostring(customDimensions['Question'])| summarize Count=count() by question| top 100 by Count | project question, Count // 从特定时间戳以来的热门提问requests| where url endswith "generateAnswer" and timestamp > datetime('2019-05-12 00:00:00') | project timestamp, id, name, resultCode, duration| parse kind = regex name with *"(?i)knowledgebases/"KbId"/generateAnswer"| join kind= inner (traces | extend id = operation_ParentId) on id| extend question = tostring(customDimensions['Question'])| summarize Count=count() by question| top 100 by Count | project question, Count // 所有时间的热门提问requests| where url endswith "generateAnswer" | project timestamp, id, name, resultCode, duration| parse kind = regex name with *"(?i)knowledgebases/"KbId"/generateAnswer"| join kind= inner (traces | extend id = operation_ParentId) on id| extend question = tostring(customDimensions['Question'])| summarize Count=count() by question| top 100 by Count | project question, Count 作为额外的好处，你可以在运行查询后点击图表按钮，以图表形式查看信息。
