RegEx help

[Wonder Fef]

Hello all,

I've read the RegEx documentation, but it's too hard for me, so I'm now
asking for your help.

I've added a search engine to my application, but I'd like to add this
feature :

For example:
The user is searching for "M.G.M", if this record exists as "MGM", Valentina
should find it.
In another way, if the user is searching for "MGM", if the record exist as
"M.G.M", Valentina should find it

I know that there is a mean to tell RegEx to include one character wherever
it is or it is not.

Thank you very much in advance for your help
Eric
