Chances are you already use Google frequently, but here are some tricks that can help save you time and find relevant sources.
This is when you conduct a search on only one site which can be useful for very specific, targeted searching. Once you target a site, use keywords and phrases that are specific to the site. Let's say you want to see results about coal trains from the wwu.edu domain. In Google, you would type site:wwu.edu coal train into Google.
As another example, let's say you want to find Storify stories that about coal trains. In Google, you would type site:storify.com coal train.
One of the most useful Search Tools in Google is the time selector which you can use to get results from a specific time period (e.g. the past hour, past twenty-four hours, past week, past month, past year, and/or a custom range).
This is when you search for pages that link to a specific domain in order to discover relationships between different sites. In Google, you can do this by using the link operator link:wwu.edu. You can also add search terms to produce more exact results.
