fuzzysearch

Tiny and blazing-fast fuzzy search in Python.

Fuzzy searching allows for flexibly matching a string with partial input, useful for filtering data very quickly based on lightweight user input.

Port of fuzzysearch in JavaScript into Python.

Install

Just install using pip:

$ pip install simple-fuzzysearch

fuzzysearch(needle, haystack)

Returns true if needle matches haystack using a fuzzy-searching algorithm. Note that this program doesn't implement levenshtein distance, but rather a simplified version where there's no approximation. The method will return true only if each character in the needle can be found in the haystack and occurs after the preceding matches.

from fuzzysearch import fuzzysearch

fuzzysearch('twl', 'cartwheel') # <- true
fuzzysearch('cart', 'cartwheel') # <- true
fuzzysearch('cw', 'cartwheel') # <- true
fuzzysearch('ee', 'cartwheel') # <- true
fuzzysearch('art', 'cartwheel') # <- true
fuzzysearch('eeel', 'cartwheel') # <- false
fuzzysearch('dog', 'cartwheel') #  <- false
