• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang xay hoi. hieu ve chat ((xuc va) OR (tuc va)) ((thanh ha) or (hanh va)) luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xay hoi. hieu ve chat ((xuc va) OR (tuc va)) ((thanh ha) OR (hanh va)) luu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xay hoi. hieu ve chat ((xuc va) OR (tuc va)) ((thanh ha) or (hanh va)) luu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xay hoi. hieu ve chat ((xuc va) OR (tuc va)) ((thanh ha) or (hanh va)) luu tre*.
