Search commands by category

The search commands that make up the Splunk Light search processing language are a subset of the Splunk Enterprise search commands. The tables below list the commands that make up the Splunk Light search processing language and is categorized by their usage. Some commands fit into more than one category based on the options that you specify.

This topic links to the Splunk Enterprise Search Reference for each search command.
