• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky lang mai hoi. hieu ((ve cham) OR (vu cham)) xuc va ((hanh vai) or (hanh va)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky lang mai hoi. hieu ((ve cham) OR (vu cham)) xuc va ((hanh vai) OR (hanh va)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky lang mai hoi. hieu ((ve cham) OR (vu cham)) xuc va ((hanh vai) or (hanh va)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky lang mai hoi. hieu ((ve cham) OR (vu cham)) xuc va ((hanh vai) or (hanh va)) cuu tre*.
