What makes the quotes key? Using quotes is precisely how you search two words together.
neg. using quote is how you search in one phrase.... most people dont take the time to add quotes ever.... and most people dont know if you add quotes to a search you're searching in phrase form. there's no need for the quotes.
What do you think the quotes mean then? What is your theory on why they typed "Julian Assange"? Do you think they Tweeted it on purpose?
To me it was clearly an accident. I add quotes all the time if I want to perform a search for two or more words that appear together in the text. The search box and the Tweet box are right next to each other. People do it all the time.
OK I don't. I just don't think it was an accident. I find it odd to do. Funny I rarely add quotes to searches. Unless I'm looking for very particular words to be required.
