• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ty) or (sac ky)) nang xa hoi. hieu van chat xuc ((va dinh) OR (va tinh)) dao cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sac ky)) nang xa hoi. hieu van chat xuc ((va dinh) OR (va tinh)) dao cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) or (sac ky)) nang xa hoi. hieu van chat xuc ((va dinh) OR (va tinh)) dao cua tre*".
