A fuzzy string set data structure for approximate string matching.
In a nutshell:
1. Add data to the set (see `add`, `add_`, `addMany`, and `addMany_`)
2. Query the set (see `find`, `findMin`, `findOne`, `findOneMin`, `closestMatchMin`, and `closestMatch`)
Refer to the [Haddock docs](http://hackage.haskell.org/package/fuzzyset) for details.
## Example
```haskell
{-# LANGUAGE OverloadedStrings #-}
module Main where ```
import Control.Monad.Trans.Class (lift)
import Data.Text (Text)
import Data.FuzzySet (FuzzySearchT, add_, closestMatch, runDefaultFuzzySearchT)
findMovie :: Text -> FuzzySearchT IO (Maybe Text)
findMovie = closestMatch
prog :: FuzzySearchT IO ()
prog = do
add_ "Jurassic Park"
add_ "Terminator"
add_ "The Matrix"
result <- findMovie "The Percolator"
lift (print result)
main :: IO ()
main = runDefaultFuzzySearchT prog
```
