The File View tabbed page shows search results at the file level.
The Link View tabbed page shows search results by linking files that can be linked among

Search by Time Period
You can specify a search period to perform the search.
You can specify dates by clicking the arrow and using the calendar that appears or selecting
and entering the numbers directly.
The selectable range is from “1990/01/01 00:00” to “2037/12/31 23:59.”
When you specify a period, if any section of a file overlaps with the search period, the file
appears in the search results. Below are several examples for different search periods.
Example 1. When consecutive data files A to E all exist
File A File B File C File D File E

Files B, C, and D will appear on the file view tabbed page.
If the files are linked, files A to E are detected as a single unit and displayed on the link view
tabbed page.
Example 2. When a portion of the linked files does not exist and the search period is
within that portion

If the data files are linked, no file links are displayed on the link view tabbed page.
