Hi guys,

I'm trying to find some sort of a good, fuzzy string matching algorithm. Direct matching doesn't work for me — this isn't too good because unless my strings are a 100% similar, the match fails. The Levenshtein method doesn't work too well for strings as it works on a character level. I was looking for something along the lines of word level matching e.g.

String A: The quick brown fox.

String B: The quick brown fox jumped over the lazy dog.

These should match as all words in string A are in string B.

Now, this is an oversimplified example but would anyone know a good, fuzzy string matching algorithm that works on a word level.

Thanks in advance.
