Python library for fast fuzzy search over a big file written in Rust
Table of Contents
About The Project
Fastzy is a library written in Rust that can search through a file looking for text based on its distance (Levenshtein). For measuring the Levenshtein distance, the library uses mbleven's algorithm. In situations where the requested distance exceeds 3, where mbleven is slower, Wagner-Fischer is used instead of mbleven. This library loads the whole file into memory, and creates a lightweight index based on the length of the lines. The result is that only potential lines are looked up, opposed to a large number of lines.
Built With
Performance
| Library | Function | Time |
|---|---|---|
| polyleven | polyleven.levenshtein('text') | 8.48s |
| fastzy | fastzy.search('text) | 0.003s |
Installation
pip3 install fastzy
Usage
import fastzy
# open a file and index it in memory
searcher = fastzy.Searcher(
file_path='input_text_file.txt',
separator='',
)
# search for the input text 'text' with the distance of 1
searcher.search(
pattern='text',
max_distance=1,
)
['test', 'texts', 'next']
