This is how I have done something similar:
In Search.pm find the line:
$args->{query} =~ s,^\s*|\s*$,,g;
after this add:
$args->{query} =~ s,&,and,g;
and then in the record for AT&T add ATandT in a field which is searched - I have added a keyword field to my Links table so that I can add extra words which I don't want to include in the description but which I want that listing returned for.
