• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sai ky) or (cac ky)) ((nang ma) OR (sang ma)) hoi. hieu ve cac xuc va hanh du cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sai ky) OR (cac ky)) ((nang ma) OR (sang ma)) hoi. hieu ve cac xuc va hanh du cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sai ky) or (cac ky)) ((nang ma) OR (sang ma)) hoi. hieu ve cac xuc va hanh du cua tre*".
