N-gram Fuzzy Search

The `ngram` library provides a `set` subclass for efficient fuzzy searching of members based on N-gram string similarity. It extends Python's built-in `set` class and offers static methods to compare string pairs. The N-grams are character-based, not word-based, focusing on string similarity rather than language modeling. The library is actively maintained, with the current version being 4.0.3, and updates are released as needed.
