• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach tu) or (cach tu)) hoang xa hoi. hieu ((van cam) OR (van nam)) xuc va thanh tai cac treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tu) OR (cach tu)) hoang xa hoi. hieu ((van cam) OR (van nam)) xuc va thanh tai cac treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tu) or (cach tu)) hoang xa hoi. hieu ((van cam) OR (van nam)) xuc va thanh tai cac treo".
• Adding a wildcard symbol may retrieve word variants: tu ((sach tu) or (cach tu)) hoang xa hoi. hieu ((van cam) OR (van nam)) xuc va thanh tai cac treo*.
