Here's an trick that reduces the noise in the results (the first time I tried your link the results were
very noisy, second and subsequent times not bad at all): pick a section of text that doesn't include quotes, ideally bridging two sentences, e.g. "in U.S. history. In Act II, we" and then add site:wsj.com, ideally trim browser specific stuff and you get something like
http://www.google.com/search?q=%22in+U.S.+history.+In+Act+II...
