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