• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach y) or (sac ky)) sang mai hoi. hieu ve cam ((xuc va) OR (tuc va)) dinh lai chau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach y) OR (sac ky)) sang mai hoi. hieu ve cam ((xuc va) OR (tuc va)) dinh lai chau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach y) or (sac ky)) sang mai hoi. hieu ve cam ((xuc va) OR (tuc va)) dinh lai chau tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach y) or (sac ky)) sang mai hoi. hieu ve cam ((xuc va) OR (tuc va)) dinh lai chau tre*.
