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