Message-ID: <CAP_800pZ4C7g9JJSO6gBp7rEd578HqxSoKmRbO9ZuMm29t-p-A@mail.gmail.com> (raw)
In-Reply-To: <20111223012153.GA16761@siouxsie>
Please read the pcre man page on partial matching: "man pcrepartial".
The reason why e.g. "hsgshsn" gives you a partial match is that it
ends in "n", and the pattern starts with "n". This means that the
subject string might match the pattern "node" if it were extended
appropriately.
Regards,
Markus
