   ### Requirement or improvement
   - Please describe your requirements or improvement suggestions.
   
   When using ElasticSearch as the storage backend, no data on the date 
selected by the UI will cause oap-server to throw a large number of 
`index_not_found_exception` exceptions, and the UI interface will not display 
any error prompts.

   **Therefore, should the UI date selection component restrict the selectable 
dates to ensure that the user selects a date without data and the aop server 
cannot return data?**
