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