Purpose
-------
The purpose of this project is to get a quick snapshot of how you build real-world software. Please
build this as if it was going to be deployed to production and users were really going to use it.

That said, do not worry about operational issues. Assume load-balancing, auto-scaling, sharding, or
any other issue related to running the product has been solved for you, or can be solved later.

Project
-------
Write a simple search web app with type-ahead behavior, with data sourced from a document database.
The type-ahead should show only documents that match what the user has currently typed. Once the
user has committed to the search, a list of titles and descriptions for documents should be displayed
on the page.

The app should have two pieces:
- A back-end API server that handles document metadata. The back-end server can be written in any language and framework.
- A front-end web app that talks to the API server. The front-end app should be written in React.

Assumptions
-----------
- The document DB can have over one million documents.
- Do not focus on the document DB technology or implementation. Define the models, but mock or back them
with any store you want -- even an in-memory array.
- The API does not need to be secured via user login, session management, or any other access controls.
- Use any tools or libraries you would find useful.
- This should take roughly four hours to build. If it's taking too long, please reach out before investing
more time.
