potresti rientrare in questo caso:
A natural language search interprets the search string as a phrase in natural human language (a phrase in free text). There are no special operators. The stopword list applies. In addition, words that are present in more than 50% of the rows are considered common and do not match. Full-text searches are natural language searches if no modifier is given.
