Why would I have to do that? Not to mention that no, I don't think quotes are respected by google any more.
For example, this search without quotes doesn't mention Dennis Ritchie's NYTimes obituary on the first page of results:
https://www.google.com/search?q=became+more+interested+in+co...
Add quotes and the obituary becomes the first result:
https://www.google.com/search?q=%22became+more+interested+in...
They're not saying quotes never work, they're saying sometimes you use quotes and google returns a page that doesn't include the quoted word.
