"Lately"? I've been unable to get the desired domain out of Google for over a year unless I add its name to my query, and often "domain.com" is required. True of Bing, too, and this is why I'm so disappointed by both anymore.
Increasingly I'm just learning to save every article I might ever want to read again to Evernote via a bookmarklet or plugin thing for the browser, because I can never go back and find them in any search engine. I've helped a few friends set this up for themselves after they complain that "I did the exact same search and the site wasn't there anymore."
Getting back to the topic, I just cannot find these people who actually want Google to remind them Amazon exists. I can find people who type everything into the URL bar, and that may make it SEEM like they are thrilled to have Amazon come up in Google searches. But I think Google would be wise to look for a way to distinguish searchers coming from the URL bar and searchers using the search field of their browser (or a search page). As far as I can tell, the URL bar searchers want really obvious things like Amazon and are merely using Google like a bus to get there, and the people who search Google intentionally are probably looking for the not-so-obvious.
