# 🐕 PyTerrier: Doc2Query and Doc2Query−−

This is a demonstration of [PyTerrier's Doc2Query package](https://github.com/terrierteam/pyterrier_doc2query). Doc2Query generates
queries for a document, which can then be appended to a document's text before indexing to boost important terms and add missing terms.

Doc2Query functions as a `D→D` (document-to-document) transformer and can be used in pipelines accordingly.
