A package for creating Spectral Bloom filters for static sites

Sthir

Search using spectral bloom filters in static sites

Sthir can create memory efficient search feature for your static website. Sthir is equipped with an user friendly command-line interface. In two steps you can build a working search page for your website!

Description

Sthir is a library to create search functionality for your static websites. It scans your html pages for words and indexes these words in an efficient data structure called Spectral Bloom Filters. Spectral Bloom Filteres differs from regular ones as they can store counts for each hash (it can estimate, at minimum, how many times a hash was indexed). We are using an efficient base 15 decoding to compress and transfer the bloom filters at client side. Our goal can be described with a simple equation:

Less Memory Footprint + Term Frequency Knowledge = Perfect Search Functionality for Static Sites!

Installation

sthir runs on Python 3.5 or above.

Installation with pip via PyPI for OS X , Linux and Windows:

pip install sthir

To check installation run the following command:

sthir -h

If you see the help messages without any error then the installation was successful.
