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