• Performing a fuzzy search may retrieve terms with similar spellings: ((te sai) OR (te bai)) ky lang ha hoi. hieu ((va cam) or (va cham)) luc va hanh tai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sai) OR (te bai)) ky lang ha hoi. hieu ((va cam) OR (va cham)) luc va hanh tai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sai) OR (te bai)) ky lang ha hoi. hieu ((va cam) or (va cham)) luc va hanh tai cua tu".
• Adding a wildcard symbol may retrieve word variants: ((te sai) OR (te bai)) ky lang ha hoi. hieu ((va cam) or (va cham)) luc va hanh tai cua tu*.
