• Performing a fuzzy search may retrieve terms with similar spellings: thu sach y ((hang x) or (nang x)) hoi. hieu ve cam tuc ha thanh ((van cua) OR (vang cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y ((hang x) OR (nang x)) hoi. hieu ve cam tuc ha thanh ((van cua) OR (vang cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y ((hang x) or (nang x)) hoi. hieu ve cam tuc ha thanh ((van cua) OR (vang cua)) tre".
• Adding a wildcard symbol may retrieve word variants: thu sach y ((hang x) or (nang x)) hoi. hieu ve cam tuc ha thanh ((van cua) OR (vang cua)) tre*.
