• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang mai hoi. lieu ((va nam) or (van nam)) thuc xa hanh ((tai cuu) OR (tai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang mai hoi. lieu ((va nam) OR (van nam)) thuc xa hanh ((tai cuu) OR (tai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang mai hoi. lieu ((va nam) or (van nam)) thuc xa hanh ((tai cuu) OR (tai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang mai hoi. lieu ((va nam) or (van nam)) thuc xa hanh ((tai cuu) OR (tai cua)) tre*.
