• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky ((tang ma) or (dang xay)) hoi. hieu ((ve cam) OR (ve cham)) duc ban hanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((tang ma) OR (dang xay)) hoi. hieu ((ve cam) OR (ve cham)) duc ban hanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((tang ma) or (dang xay)) hoi. hieu ((ve cam) OR (ve cham)) duc ban hanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: su sac ky ((tang ma) or (dang xay)) hoi. hieu ((ve cam) OR (ve cham)) duc ban hanh hai cua tre*.
