Hey Mike! That's a good tip, I like that one (I always forget to use it though for some reason, so thanks for helping me rediscover it!) but it can be a little pollution high. If you search for a particular topic on a site, you may find hundreds of hits returned for what amounts to roughly a half dozen pages that have lots of tags. That said, it IS nice to have to wade through this kind of pollution rather than the completely irrelevant stuff.
ex. I think there are about 8 relevant posts on tension on my,... er... Arctic's blog...
if I search tension on the site:
https://www.google.ca/search?q=tensi...haicarcane.com
I get 170 hits.
There are 98 posts on the site in total.
ETA: OK, my search says that there are 37 posts with the word tension in them... apparently there's a little stress in my life?
