• Performing a fuzzy search may retrieve terms with similar spellings: vu sach y ((nang xa) or (nang ma)) hoi. lieu va cham luoc va ((hanh di) OR (hanh vi)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y ((nang xa) OR (nang ma)) hoi. lieu va cham luoc va ((hanh di) OR (hanh vi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y ((nang xa) or (nang ma)) hoi. lieu va cham luoc va ((hanh di) OR (hanh vi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sach y ((nang xa) or (nang ma)) hoi. lieu va cham luoc va ((hanh di) OR (hanh vi)) cua tre*.
