IMPORTFEED("https://news.google.com/rss/search?q="Sony")
I'm query google news for the keyword "Sony" and in the IMPORTFEED formula, I want to only bring back unique headlines. I want to exclude duplicate headlines even if they are published by different news outlets.
For example, if the "New York Times and the New Yorker Magazine both published the headline "Sony is Awesome" then I want the IMPORTFEED to bring back only 1 of those headlines and it doesn't matter which publisher it wishes to use.
