    /v[ _]?i[ _]?a[ _]?g[ _]?r[ _]?a/i

The /i bit at the end is for case-insensitivity. If your regex engine
doesn't supoort this, then use something like the following instead:

    [vV][ _]?[iI][ _]?[aA][ _]?[gG][ _]?[rR][ _]?[aA]

The ? means match 0 or 1 times. Again, if that's not supported, you
may be able to use something like {0,1} instead.
