Preview Search
This feature helps to search data through large archives. It breaks the selected range of time into smaller
time increments and displays these increments as separate Items. For instance, it breaks a month period
into ten 3-days periods displaying them as separate Items, which makes it possible to locate a specific
event in one of these periods (then breaking this period into nine 8-hour periods and so on). Finally
location of a specific event in archive may take 3-5 such iterations for initial period of several months.
