• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach hay) or (sach haya)) dang xay hoi. hieu ((ve cam) OR (va cam)) xuc van hang vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach hay) OR (sach haya)) dang xay hoi. hieu ((ve cam) OR (va cam)) xuc van hang vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach hay) or (sach haya)) dang xay hoi. hieu ((ve cam) OR (va cam)) xuc van hang vi cua tre*".
