Azure搜索统计数据Power BI

Question

我正在使用存储帐户将Azure搜索统计信息与当前设置一起收集超过一周

和Power BI查看报告。问题是，即使我导入数据20天，我也无法在“随时间变化的报告”中看到它，但只有一天，无论我选择的是什么时期。

此类报告的数据导入或/和日期范围选择的正确方法是什么？感谢的

问题是由一些包含无效转义序列（\ ^和\〜）的搜索项的查询引起的，这会导致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
• 在发送查询之前转义反斜杠（\）
• 从JSON blob本身删除有问题的字符

如果这些选项不适合您，您将无法使用Power BI内容包，但仍可以在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，即使只有一个有问题的查询，它也会忽略完整的文件（1小时的数据）

Power BI Desktop查询：

• ACCOUNTNAME ：您的存储帐户名称
• DAYS 数据天数
