How can I include a "comma" in a Google nGram search?
My problem is that I want to search for phrases like, "Yes, I do ." but Google nGrams uses commas to break up query terms, so it returns a comparison of the phrases "Yes" and "I do .". (My apologies if this question seems off-topic. I ask here because Google nGrams is an important tool for ELU users, so we need to know how to get the most out of it.)
