• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh ((y tang) OR (ky tang)) xa hoi. hieu ((ve dao) or (de dao)) duc manh anh van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ((y tang) OR (ky tang)) xa hoi. hieu ((ve dao) OR (de dao)) duc manh anh van cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ((y tang) OR (ky tang)) xa hoi. hieu ((ve dao) or (de dao)) duc manh anh van cua tre".
• Adding a wildcard symbol may retrieve word variants: thuat lanh ((y tang) OR (ky tang)) xa hoi. hieu ((ve dao) or (de dao)) duc manh anh van cua tre*.
