 A privacy-preserving search system based on [MIT's Tiptoe paper](https://people.csail.mit.edu/nickolai/papers/henzinger-tiptoe.pdf). This implementation allows you to search through data while maintaining query privacy - the server never learns what you're searching for. For more details, see our [blog](https://blog.exolabs.net/day-8/).
