At what point do I add n-grams? Does the order in which I add n-grams affect exact phrase queries later? My questions are (1) Should I add all the 1-grams followed by 2-grams followed by 3-grams..etc sentence by sentence OR (2) Add all the 1 grams of entire document first before starting 2-grams for the entire document? What is the general accepted notion of adding n-grams of a document? thanks, Rajesh
