• Performing a fuzzy search may retrieve terms with similar spellings: te sach v nang xa hoi. hieu van ((hau loc) or (cham o)) va dan ((di cua) OR (de cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang xa hoi. hieu van ((hau loc) OR (cham o)) va dan ((di cua) OR (de cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang xa hoi. hieu van ((hau loc) or (cham o)) va dan ((di cua) OR (de cua)) te*".
