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