I can't see any real advantage of storing n-grams explicitly. Just index the document and use phrase queries. Order is significant with phrase queries if I recall correctly, although you can use SpanNearQueries to look for unordered ngrams, although I don't know why you would want to! Perhaps if you explain a little more about what you are trying to achieve more generally, we can confirm that you don't need to mess with explicit indexing of indexing.
