Fast Keyword extraction usingAho–Corasick algorithm and Tries.

Flash is a Golang reimplementation ofFlashtext,

This is meant to be used when you have a large number of words that you want to:

• extract from text
• search and replace

Flash is meant as a replacement for Regex, which in such cases can be extremely slow.

import"github.com/dav009/flash"words:=flash.NewKeywords()words.Add("New York")words.Add("Hello")words.Add("Tokyo")foundKeywords:=words.Extract("New York and Tokyo are Cities")fmt.Println(foundKeywords)// [New York, Tokyo]

As a reference using go-flash with 10K keywords in a 1000 sentence text, took 7.3ms,while using regexes took 1minute 37s.

This is a toy-project for me to get more familiar with GolangPlease be-aware of potential issues.
