There are a lot of Google search tricks out there. OK, not exactly tricks, but functions that aren't obvious but are super useful. One of my favorites is the site: command. It tells Google to only return results from a particular web site. If a site has a poor quality search feature, then using Google is a quite useful alternative.
For example, if I'm looking for WCN's annual report, the site search lists 2013 as the top hit. But if I use Google site search, I get all of them. (2016 is the third result for some reason, but at least it is there.)

You can also use it to browse all the images on a site. I find this useful for getting a high-res logo, or for pulling down an image that I can use in promoting the site.
