As the Search feature retrieves data, it displays a progress bar to show its status, including the percent of data received. Rather than attempting to read all data at once, Search gathers data in chunks of time. The progress bar shows the time range from which the results are currently being retrieved.
You can pause the search and restart as needed.
NOTE:When performing a search with two or more identical queries the number of events returned for the second search will correspond to the next chunk of data. If you pause then resume the search, the first search will be moved to the next chunk as well, maintaining the same number of events retrieved. The identical queries can contain either one of the built-in queries or a custom query.
