• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((y nang) or (ky nang)) xa hoi. hieu van ((lam tuc) OR (lam thuoc)) va thanh vinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y nang) OR (ky nang)) xa hoi. hieu van ((lam tuc) OR (lam thuoc)) va thanh vinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y nang) or (ky nang)) xa hoi. hieu van ((lam tuc) OR (lam thuoc)) va thanh vinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: su sach ((y nang) or (ky nang)) xa hoi. hieu van ((lam tuc) OR (lam thuoc)) va thanh vinh cuu tre*.
