A query pipeline is a set of statements which define how queries and other operations should be executed.

A non-exhaustive list of operations performed by the statements using the query pipeline includes:

Pre-processing and post-processing the query
Defining query extensions
Defining a thesaurus
Adding query ranking expressions (QREs) to the query
Adding top results to the query
… and many more.

These statements are defined using the Query Pipeline Language.

When a pipeline is modified, it’s automatically reloaded for the next query.
