Regex filter not working #21

Closed ghost closed 13 years ago

Either that or I am not using it correctly.

The keyword 'ipad?' will effectively remove all posts with 'ipad?' in them, but the keyword '/ipad[ ][?][s]/' will not. Am I using it wrong?

What are you trying to match? That regular expression is not valid, are you trying to match ipad, ipad?, ipads? If so you should be using regex word boundaries. Something like this. Which will use word boundaries and match ipads.

/\\bipad[s]?\\b/

Ok, I'll use that, thanks!

I was trying to match ipad, ipad , ipads, ipad?

Yea, \b is a word boundary, it matches boundaries that are non word (\W) characters. Since we added a "[s]?" which is an optional s, we are matching ipads with that.
