• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ty lang) or (tay lang)) ha hoi. hieu qua cam ((xuc va) OR (tuc va)) thanh ha cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty lang) OR (tay lang)) ha hoi. hieu qua cam ((xuc va) OR (tuc va)) thanh ha cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty lang) or (tay lang)) ha hoi. hieu qua cam ((xuc va) OR (tuc va)) thanh ha cua viet".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty lang) or (tay lang)) ha hoi. hieu qua cam ((xuc va) OR (tuc va)) thanh ha cua viet*.
