Except now Google are trying to make their search engine respond to more natural language and so the established search methods like "domain keyword specific-keyword" are often less successful than trying to think of a more human, but not complex, question that might be commonly asked.

Particularly, of course, they no longer care whether results include your required words.

One has to learn and re-learn how to get the best from these systems.

Aside, I'm impressed with Alexa on FireTV, but until it enters data in to the apps, and searches within media libraries, it remains a novelty.
