Engineer Class Lab 4.1 - Missing data

For Item 9-11, I ran load_webtraffic.sh, created a dataview for web_traffic index and used @timestamp as the time field. I only found 1456190 hits from Apr 1, 00:00:00 thru Apr 30, 23:30:00 instead of 1462658 hits in the same range.

How shall I do for the next step? Can I re-run the script?

Apparently there is a bug in Elasticsearch.
If searching from Mar 31 thru Apr 30 then there will be 1,462,658 hits, otherwise from Apr 1 thru Apr 30 will be 1,456,190 hits only.
