Default WP search excluding specific characters, is it possible?

I would like to know if it possible to customize the default search module of WordPress.
I’ve a website dealing with teams and teams’ news.

Some of those teams has their names written like this

• H.M.S.
• L.A. Dream
• N.Y. Invaders

I would like that the search modules could be able to manage those teams in the results even if i look for strings like HMS, or LA Dream, or NY, instead of filling the characters with dots. Does anybody has some suggestion, or know a WP trick that at the moment i’m not aware of?

Thanks in advance
