Automatic lookups apply a lookup to every search automatically based on a sourcetype, without needing to add the `| lookup` command. These are configured in Settings > Lookups > Automatic lookups.
`inputlookup` reads an entire lookup table as if it were search results. This is useful for browsing the lookup file or using it as the primary data source.
`outputlookup` writes search results to a lookup table, letting you dynamically update lookup content from your searches.
