# Default Search Macro

By default, the ElastiFlow App for Splunk comes with a predefined `default_index` search macro. You can view the default index search macro by going to: Settings -> Advanced search -> "Search macros"

The `default_index` search macro defaults to `index="elastiflow*"`. This search macro will automatically update the `index=name` for each visualization. You can view any search in by clicking the magnifying glass next to a visualization. As you can see below this search references the `default_index` search macro.
