• Performing a fuzzy search may retrieve terms with similar spellings: pu cac ky nang xa hoi. hieu va cam ((luc va) or (loc va)) ((tinh da) OR (tinh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: pu cac ky nang xa hoi. hieu va cam ((luc va) OR (loc va)) ((tinh da) OR (tinh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "pu cac ky nang xa hoi. hieu va cam ((luc va) or (loc va)) ((tinh da) OR (tinh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: pu cac ky nang xa hoi. hieu va cam ((luc va) or (loc va)) ((tinh da) OR (tinh va)) cua tre*.
