Well, I wouldn't say that * is redundant.. however, I would say this
entire rule is silly and doesn't do what you want, and it's a little
ambiguous what you're really trying to do.
The whole rule devolves to being any empty regex (//) if you express the
*'s as {0}, meaning this should match *any* text. I highly doubt that's
what you meant.
Also, you've put the words inside [], which turns them into character
classes.
[win] will match a single character. a w, an i or an n, not the word
"win". I doubt that's what you want either.
You probably meant to do something like this:
header LR Subject =~ /
independent.*\bopportunity\b.*\bluxury\b.*\bcowhides\b.*\bwin\b.*\bmoney\b.*\brep\b.*\bsave\b.*/i
But that will only match if all the words are used IN THAT ORDER.
If you want to match all of them being used in arbitrary order, you'll
have to use multiple rules and combine them with a meta rule.
Or perhaps you were looking to detect if any one of them was used, which
would be this rule:
header LR Subject =~ /
\b(?:independent.|opportunity|luxury|cowhides|win|money|rep|save)\b/i
Probably very false positive prone, but that works.
