• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((nang ma) or (tang ma)) hoi. lieu nha nam thuoc xa ((hanh tai) OR (thanh tai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((nang ma) OR (tang ma)) hoi. lieu nha nam thuoc xa ((hanh tai) OR (thanh tai)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((nang ma) or (tang ma)) hoi. lieu nha nam thuoc xa ((hanh tai) OR (thanh tai)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((nang ma) or (tang ma)) hoi. lieu nha nam thuoc xa ((hanh tai) OR (thanh tai)) cuu tre*.
