Populating summary indexes with saved
searches
A search to populate a summary index is much like any other saved search
(see Chapter 2 , Understand Search , for more detail on creating saved searches).
The differences are that this search will run periodically and the results will be stored
in the summary index. Let's build our first summary search by following these steps:

1. Start with a search that produces some statistic:

source="impl_splunk_gen" | stats count by user

2. Save this search as summary - count by user .

3. Edit the search in Manager by navigating to Manager | Searches and reports

| summary - count by user . The Save search... wizard provides a link to the
manager on the last dialog in the wizard.

4. Set the appropriate times. This is a somewhat complicated discussion. See the

How latency affects summary queries section discussed later.
