Strange behavior with advanced catalog search (regex)

QuantumBeep · 02-21-2011, 03:10 AM

Consider the following title search:

^[\W0-9\s]+

I'd expect that to find all books whose titles begin with non-alphanumerics, numerals, and whitespace.

And so it does.

It also finds all books whose titles begin with "w" or "s". That's a surprise.
Any thoughts?
