I think all of the above is the work of the devil. I am very knowledgeable on boolean logic. I understand the use of NOT AND OR and parenthesis. If I want a search engine to search for (cat OR kitten) AND licking AND NOT (pu$$y OR shaved OR "rug munching") - then *THAT* is what I want the search engine to do! But NOOOOO - the great google believes it *knows* what I really want and what I tell it to do is completely irrelevant!

I use a plug-in for Chrome that forces "Verbatim" to be on in google searches. That helps a little, but it still doesn't give me the search result I could get if true boolean logic was allowed. And image searches are even worse - there is NO verbatim and image search won't even recognize a quoted phrase. With image search "cat licking" will return exactly the same results as cat OR licking - freaking useless!!
