• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu xang xa hoi. ((thien van) OR (thi van)) lam ((xuc ban) or (cuc ban)) banh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu xang xa hoi. ((thien van) OR (thi van)) lam ((xuc ban) OR (cuc ban)) banh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu xang xa hoi. ((thien van) OR (thi van)) lam ((xuc ban) or (cuc ban)) banh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach thu xang xa hoi. ((thien van) OR (thi van)) lam ((xuc ban) or (cuc ban)) banh vi cua tre*.
