• Performing a fuzzy search may retrieve terms with similar spellings: (( su sach cha me gioi ((con hong) OR (con song)) minh ) or ( tu sach cha me nguoi con thong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach cha me gioi ((con hong) OR (con song)) minh ) OR ( tu sach cha me nguoi con thong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach cha me gioi ((con hong) OR (con song)) minh ) or ( tu sach cha me nguoi con thong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( su sach cha me gioi ((con hong) OR (con song)) minh ) or ( tu sach cha me nguoi con thong tin ))*.
