• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (cac ky)) tang xa hoi. hieu van nam mua va kinh ((van cuu) OR (van cu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (cac ky)) tang xa hoi. hieu van nam mua va kinh ((van cuu) OR (van cu)) tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (cac ky)) tang xa hoi. hieu van nam mua va kinh ((van cuu) OR (van cu)) tre*.
