• Performing a fuzzy search may retrieve terms with similar spellings: te ((anh thuc) or (cac thu)) nano xa hoi. hieu van hac xuc va thanh ((via cua) OR (gian cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((anh thuc) OR (cac thu)) nano xa hoi. hieu van hac xuc va thanh ((via cua) OR (gian cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((anh thuc) or (cac thu)) nano xa hoi. hieu van hac xuc va thanh ((via cua) OR (gian cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te ((anh thuc) or (cac thu)) nano xa hoi. hieu van hac xuc va thanh ((via cua) OR (gian cua)) tre*.
