Compare strings which resembles each other

[Gulshan Babajee <gulshan(dot)babajee(at)parabolemaurice(dot)com>]

Hy, I have a table containing some rows. Each row contains a field name
which is of type String.

For example:
in row1 string1 is "Adieu Poulet",
in row2 string2 is "Adieu a Poulet",
in row3 string3 is "Adiue Poulet",
in row4 string4 is "Adieu Pouleet", etc..
(That is each string resembles each other a bit, they are somewhat similar
to each other)

What type of query should I make so as it return me all these string. That
is I watn a query which return me strings which are similar or somewhat
similar to each other.

thanks in advance
