• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang x hoi. hieu van ((cham xuc) OR (cham soc)) ban ((anh de) or (hanh de)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x hoi. hieu van ((cham xuc) OR (cham soc)) ban ((anh de) OR (hanh de)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. hieu van ((cham xuc) OR (cham soc)) ban ((anh de) or (hanh de)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. hieu van ((cham xuc) OR (cham soc)) ban ((anh de) or (hanh de)) cua tre*.
