I think given a given search algorithm there is an art to searching effectively with that algorithm. For example for a long time you’d search based on the words you expect in an answer to the question. As Google got more into the “reading the search query as a question” mode you had to shift a bit to framing the query with words from a question that would typically be asked to get the search results. I suspect some of the friction between switching search providers is that we unconsciously get tuned to what terms to use to get the answers we want.
