# Diagrams

Pipeline diagrams for indexing and retrieval

TRS implements basic indexing and retrieved-augmented generation pipelines.

#### Planning

Planned upgrades to the pipelines include:

* Addition of summary index
  * Summarized text is stored in it's own index
  * Retrieval can query both the document and summary index then synthesize answer across both sources
* Better management of previously processed URLs
