• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly ((nang xa) or (nang x)) hoi. hieu ve cham ((tuc va) OR (truc va)) hanh doi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly ((nang xa) OR (nang x)) hoi. hieu ve cham ((tuc va) OR (truc va)) hanh doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly ((nang xa) or (nang x)) hoi. hieu ve cham ((tuc va) OR (truc va)) hanh doi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ly ((nang xa) or (nang x)) hoi. hieu ve cham ((tuc va) OR (truc va)) hanh doi cua tre*.
