• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty xang xa hoi. hieu van lam luc va hang ((((va cua) OR (ca cua))) or (va chua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty xang xa hoi. hieu van lam luc va hang ((((va cua) OR (ca cua))) OR (va chua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty xang xa hoi. hieu van lam luc va hang ((((va cua) OR (ca cua))) or (va chua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty xang xa hoi. hieu van lam luc va hang ((((va cua) OR (ca cua))) or (va chua)) tre*.
