Some text matching questions

[Vendettta]

I tried it (not sure I did it right), with these results:

pink((s|)
Sample Text: 30000 bytes
Successful Matches: 27
Avg time: 2.969000 (milliseconds)

((pink|pinks)
Sample Text: 30000 bytes
Successful Matches: 27
Avg time: 3.140000 (milliseconds)

So yes, a bit faster.
It's a little comforting that (pink|pinks) will work though because the other method still doesn't make sense to me. It seems like it should be pink(|s) if anything.
