So far, rebuilding a collection has taken only a few seconds. Once generating embeddings takes hours, you need to get the design right before ingesting your data.

**Follow-along code**: [Module 4 notebook](https://github.com/qdrant/examples/blob/master/course/beginners/Module4.ipynb)

#### Overview

> Module 3 showed you how to combine dense and sparse retrieval. Now you'll use those pieces to design a system that can grow beyond a small collection. You'll decide what to store and embed, see what changes as the collection grows, and choose when to add more machines, when to put a language model on top, and where to run Qdrant. By the end, you'll have designed a news search system and five questions to use on a system of your own.
