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