Regular Expression: Match with... tolerance

[teo]

Hallo,

I'd like to match a given string, let's say
fghilm
in a bigger string, let's say
abcdefghilmnopq

but I'd like to have also a toleranche, let's say
about 1 chars

so if we have if in the bigger string

one different char, like z in
abcdefghzlmnopq
or
one missing char, like g in
abcdefhilmnopq

the match happens the same.

-------

Does RegEx have this feature
(even better if the tolerance could be customizable,
that is one or two or three chars... of tolerance)?

If not,
any other solution/snippet of code/web page link?

This sort of "fuzzy" matching can be mimiced with wildcards and the
reptition constructs, but it's a bit kludgy.

Probably best to use full-text searching for this sort of matching. Or
perhaps Soundex matching if it's readable text.
