• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((((v nang) OR (va nang))) or (vu nang)) xa hoi. hieu va thai do va hanh dien cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((((v nang) OR (va nang))) OR (vu nang)) xa hoi. hieu va thai do va hanh dien cuc tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((((v nang) OR (va nang))) or (vu nang)) xa hoi. hieu va thai do va hanh dien cuc tre*".
