The edge_ngram tokenizer first breaks text down into words whenever it encounters one of a list of specified characters, then it emits N-grams of each word where the start of the N-gram is anchored to the beginning of the word. Elasticsearch just search for the terms the user has typed in, for instance: Quick Fo. The edge_ngram_filter produces edge N-grams with a minimum N-gram length of 1 (a single letter) and a maximum length of 20.
