Greetings, monks. I have come in search of wisdom that I have not found anywhere else; neither the the Camel book nor Googling has come up with an answer to my question and I hope that it may be answered here. I am trying to find multiple words in a sentence, and if I find them, act accordingly. To wit, I wrote: 
if ($sentence =~ /foo/gis && $sentence =~ /bar/gis)
{
   # do something further with $sentence 
}

But it is wrong, the second expression is always false, even if the sentence does contain a "bar". I rewrote it to say: 
if ($sentence =~ /foo/gis)
{
   if ($sentence =~ /bar/gis)
   {
      # now do something with the sentence
   }
}

but that doesn't work either! The only way I could get it to work was: 
if ($sentence =~ /foo/gis)
{
    my $final_test = $sentence;
    if ($final_test =~ /bar/gis)
    {
       # *now* do something with the sentence...
    }
}

I apologize if this is a real "duh" question; it seemed like it would make sense to me (a C++ programmer) but the second try really confused me as I figured it surely couldn't fail, it was just doing another search. I beg wisdom and mercy for my cluelessness. Thank you, Tacho
