• Performing a fuzzy search may retrieve terms with similar spellings: thu sac kho tang ha noi. hieu ve cham vuc ((van thanh) OR (ban thanh)) ((ve cum) or (te cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac kho tang ha noi. hieu ve cham vuc ((van thanh) OR (ban thanh)) ((ve cum) OR (te cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac kho tang ha noi. hieu ve cham vuc ((van thanh) OR (ban thanh)) ((ve cum) or (te cua)) tre*".
