The search options for some sites is pretty lame, which sucks when your looking within a big site. Did you know you can use Google to search within the site?
192 Million results might sound like too many. Have you tried narrowing down your search results by using inverted commas?
Google also lets you search for file types, like powerpoint, word docs or PDF’s. Particularly handy when you no exactly what you want, like a template, but can’t find it.
