I was going to post the link that Digy posted, which suggests not to
determine a match that way.  If my understanding is correct, the scores
returned for a query are relative to which documents were retrieved by the
search, in that if a document is deleted from the index, the scores will
change even though the query did not, because the number of returned
documents are different.

If the only thing you wanted to do was to calculate how a resulting string
was to a search string, I suggest the Levenshtein Distance algorithm
http://en.wikipedia.org/wiki/Levenshtein_distance...but it doesn't seem like
that's quite what you want to accomplish based on your question.
