Not Results Found Error

[Dixie]

I have uploaded a csv dataset into Splunk, and have been able to successfully use the dataset addon and pivot my data and create visualizations. I created reports and dashboards. I then decided to explore my dataset in the investigative search (the regular search command for Splunk). Once I returned back to my dataset it reads no results found. I adjust the time to include all time still no results found. I then go check the reports and dashboards I created and I get an error no results found for each box there should be a chart.

This error happened to me three times before, and I had to recreate all of my work. At the time I thought it was just a bug, not knowing what caused it. I now know I get this error every time I decided to explore my dataset in the investigative search.

Can anyone resolve this?

what is the _time you have seen when you have indexed data from csv file?

Did you change index retention for the index which data is indexed?

Do you have enough space on disk?

Yes I have changed nothing, I simply only opened my dataset in the investigative search. I did not like the format and simply went back to working in the dataset and once I created a dashboard I got the error. I  then checked all my previous dashboards and it reads the same error.
