Hello, Let's say you have an indexed text "t1 t3 t3" with shingles. The token positions are also indexed, so you get : t1 (at pos 1), "t1 t2" (pos 1), t2 (pos 2), "t2 t3" (pos 2) and t3 (pos 3).
So if you are searching with a match_phrase for "t1 t2 t3" (even if not tokenized as shingles) it will matches the document, because t1, t2 and t3 are considered next to each others (based on there recorded position) for this document.
