Azure 搜索统计 Power BI

Question

我使用存储帐户以当前设置收集 Azure 搜索统计信息超过一周

和 Power BI 来查看报告。问题是，即使我导入了 20 天的数据，我也无法在 "Search over time report" 中看到它，但无论我选择的时间段如何，我都只能看到一天。

什么是正确的数据导入方式or/and 在这种报告上选择日期范围？谢谢

问题是由于某些查询的搜索词包含无效的转义序列（\^ 和 \~），导致 JSON 解析器失败。

这是 Power BI 内容包的限制。使其工作的选项如下：

发送查询前删除反斜杠
发送查询前转义反斜杠 (\)
从 JSON blob 本身中删除违规字符

如果这些选项不适合您，您将无法使用 Power BI 内容包，但您仍然可以在 Power BI Desktop 中分析数据。下面是一个为 JSON 解析器添加错误处理的查询。这种方法的局限性在于它会忽略完整文件（1 小时的数据），即使只有一个有问题的查询

Power BI Desktop 查询：
