• Performing a fuzzy search may retrieve terms with similar spellings: tu sach 7 lang ha hoi. hieu ((ve cai) or (ve cac)) ((tuc va) OR (truc va)) thanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach 7 lang ha hoi. hieu ((ve cai) OR (ve cac)) ((tuc va) OR (truc va)) thanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach 7 lang ha hoi. hieu ((ve cai) or (ve cac)) ((tuc va) OR (truc va)) thanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach 7 lang ha hoi. hieu ((ve cai) or (ve cac)) ((tuc va) OR (truc va)) thanh vi cuu tre*.
