# 🐕 PyTerrier: Retrieve

This is a demonstration of [PyTerrier's TerrierRetrieve transformer](https://pyterrier.readthedocs.io/en/latest/terrier-retrieval.html).

TerrierRetrieve functions as a `Q→R` (retrieval, query-to-result) transformer and can be used in pipelines accordingly. For example, you can
pipe the results to a transformer such as `get_text` to load the text associated with the document:

<div class="pipeline">
  <div class="df" title="Query Frame">Q</div>
  <div class="transformer attn" title="PisaRetrieve Transformer">TerrierRetrieve</div>
  <div class="df" title="Result Frame">R</div>
  <div class="transformer" title="get_text Transformer">get_text</div>
  <div class="df" title="Result Frame">R</div>
</div>
