• Performing a fuzzy search may retrieve terms with similar spellings: su xac ky tang xa hoi. hieu ve cam ((xuc van) or (xuc ban)) ((nhanh hai) OR (nhanh thai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky tang xa hoi. hieu ve cam ((xuc van) OR (xuc ban)) ((nhanh hai) OR (nhanh thai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky tang xa hoi. hieu ve cam ((xuc van) or (xuc ban)) ((nhanh hai) OR (nhanh thai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su xac ky tang xa hoi. hieu ve cam ((xuc van) or (xuc ban)) ((nhanh hai) OR (nhanh thai)) cua tre*.
