Occasionally missing data when making both gt + lte queries with a single isoformatted date

Elastic Stack Elasticsearch
5

I've the refresh_interval to 1s and it still doesn't seem to fix it.

Additional notes:
the start_time for the realtime-log query doesn't change unless the query came back with a success log because start_time gets updated as so

current_starting_time = start_time
while True:
   logs = make_query(..., start_time=current_starting_timestamp)
   
   has_new_logs = logs.get("hits", {}).get("hits") and len(logs["hits"]["hits"]) > 0
   
   if has_new_logs:
            # Update the current starting timestamp for next query (already sorted)
            current_starting_timestamp = logs["hits"]["hits"][0]["_source"]["@timestamp"]
   
   await asyncio.sleep(2)

from this, we know that when it makes the query again, it still misses first log after the initial start_time
