• Performing a fuzzy search may retrieve terms with similar spellings: te ((((sach ty) OR (sach tu))) or (sach y)) xang xa hoi. hieu ve cam xuc van hanh tai nha nuoc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach ty) OR (sach tu))) OR (sach y)) xang xa hoi. hieu ve cam xuc van hanh tai nha nuoc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ty) OR (sach tu))) or (sach y)) xang xa hoi. hieu ve cam xuc van hanh tai nha nuoc".
• Adding a wildcard symbol may retrieve word variants: te ((((sach ty) OR (sach tu))) or (sach y)) xang xa hoi. hieu ve cam xuc van hanh tai nha nuoc*.
