Open source full text search server, designed from the ground up with performance, relevance (aka search quality), and integration simplicity in mind

What is Sphinx?

Sphinx lets you either batch index and search data stored in an SQL database, NoSQL storage, or just files quickly and easily — or index and search data on the fly, working with Sphinx pretty much as with a database server. A variety of text processing features enable fine-tuning Sphinx for your particular application requirements, and a number of relevance functions ensures you can tweak search quality as well.
Sphinx is a tool in the Search Engines category of a tech stack.

We use Sphinx because it's the standard for Python documentation. As Paperless is Python-based, this only made sense.

Additionally, readthedocs.org plays very well with it, so that's your documentation hosting for you for free.

Finally, it supports ReStructuredText, which is amazingly powerful.
