I am trying to search for an exact phrase but Google returns some results that have extra characters.For example I wanna search for this exact phrase: quotation double quote But in Google results I also see: quotation (double quote) returned or even quotation. Double quotes returned. In the first one there are extra parentheses and in the second one there is extra period and also instead of quote it included quotes.How can I make sure Google returns documents with the EXACT phrase that I want?
