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