Query Processing

Query Processing steps help to better understand natural language queries and therefore improve the overall search experience.

Have a look at the Query Processing Workflow User Guide to see how those steps are used together with the Squirro Search Bar.

For information on how to create custom steps as a python engineer, see How to Create Custom Query-Processing Steps.
