Different ways to search against time
Now that we have our time indexed properly, how do we search against time?
The time picker provides a neat set of defaults for relative time.
These options search back from the present to a relative point in time,
but sometimes, you need to search over a specific period of time.
The last option, Custom time… , provides an interface that helps specify
specific times.
• Date is the first option.
If you know specifically when an event happened, you can drill down to
whatever time range you want here. The time zone here is what you have
chosen in Your account , or the system default if you didn't change it. This
may not be the time zone of the events you are looking for.
