• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty nang xa hoi. hieu ((ve cai) or (va cam)) duc va danh ((vai cua) OR (lai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. hieu ((ve cai) OR (va cam)) duc va danh ((vai cua) OR (lai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. hieu ((ve cai) or (va cam)) duc va danh ((vai cua) OR (lai cua)) te".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. hieu ((ve cai) or (va cam)) duc va danh ((vai cua) OR (lai cua)) te*.
