I should clarify that "&" is not a meaningful search operator in Google. If you enter two or more words, Google takes the "AND" concept as a given, i.e. it assumes you're looking for sites that contain all the specified words. (If you want it to search for sites that contain either term but not both, you would enter "this OR that." "This that" is implicitly "This AND that.") So I would assume that by entering the "&" symbol, you're just telling it to search for pages that actually contain that typographic symbol in their text in addition to the other words. Except that would presumably give fewer results, but in fact it gives 3,000 more than you get without it. So maybe it does have some other effect, but I'm not sure what. It's certainly not a necessary search operator.
Now that we've somewhat resolved your Janeway result, I'm still wondering how you got such a bizarrely low result for Picard.
