The Google search engine explains that When you put a word or phrase in quotes, the results will only include pages with the same words in the same order as what's inside the quotes.  Note: Only use this if you're looking for an exact word or phrase, otherwise you'll exclude many helpful results by mistake.  Example: imagine all the peopleI want to find exact phrase containing -include meaning a usage of g++ compiler. It's strange, but all search engines ignore my minus sign despite I put the phrase in double quotes in my query g++ -include optionWhy? How to find what I actually want?
