## Definition
Retrieval Precision is an evaluation metric in RAG systems measuring the fraction of retrieved document chunks that are actually relevant to answering the user query. High retrieval precision prevents prompt clutter and distraction.

## Architectural Mechanics & Deep Dive
Retrieval precision is a metric in RAG pipelines that evaluates the quality of retrieved context. It measures the ratio of retrieved document chunks that are actually relevant to the user query out of all retrieved chunks. High retrieval precision prevents the LLM context from being cluttered with distracting, irrelevant information.

## Industry Applications & Real-World Use Cases
RAG pipeline validation, chunking size optimization, and vector search evaluation.

## Frequently Asked Questions

### What is the difference between retrieval precision and recall?
Precision measures how many of the retrieved documents are relevant. Recall measures if the retriever found all the relevant documents in the database.

### How do you improve retrieval precision?
By using metadata filtering, semantic rerankers, and refining chunk size and overlap parameters.
