• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly vang xa hoi. hieu viec cua ((xuc va) or (tuc va)) ((hanh di) OR (hanh de)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly vang xa hoi. hieu viec cua ((xuc va) OR (tuc va)) ((hanh di) OR (hanh de)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly vang xa hoi. hieu viec cua ((xuc va) or (tuc va)) ((hanh di) OR (hanh de)) cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ly vang xa hoi. hieu viec cua ((xuc va) or (tuc va)) ((hanh di) OR (hanh de)) cua te*.
