(Relatively) slow Google search (2.64 seconds)

You might need to click "Search instead for" to trigger the 'correct' search.

It's also odd how:

<script[ \\to[^<](?:(?!<\\/script>)<[^<])<\\/script[ \\t]?>

runs in <0.5 seconds, whilst:

<script[ \\t]?\\b[^<](?:(?!<\\/script>)<[^<])<\\/script[ \\t]?>

runs in >2.5 seconds?

Wow, I've never seen this kind of Google search before. I wasn't able to find documentation for it — would someone be kind enough to post a link?
