				Autocomplete is made using star on a titles index (with infixes).<br />Correction
				suggest can be made inside a phrase , by trying to find a suggestion
				for each wrong typed word or word with low hits.<br /> Trigrams are
				used in the process and there are also sane checks ( based on length
				and levenshtein algorithm). <br /> It does not guarantee the new
				corrected phrase will do matching.This can be done by doing a query
				with the new phrase.
