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