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 people"
I 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" option
Why? How to find what I actually want?
