In 4.3 the search flashtime, sometimes the same query will return a full set of result rows in the events list but other times it will not.
In the UI if I navigate to subsequent pages for my search results, I will only see the indexed timestamps on the left but the data rows are empty.
If I select the table view, I can see the raw data is there. So this is not a data issue.
This intermittent display issue can happen on any search and I have even seen it on Splunk's standard "Errors in the last 24 hours" query.
This is a known issue reported under SPL-49330.
