• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh hang cua ((cong nong) OR (cong trong)) ((tinh tran) OR (tinh than)) chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh hang cua ((cong nong) OR (cong trong)) ((tinh tran) or (tinh than)) chau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh hang cua ((cong nong) OR (cong trong)) ((tinh tran) or (tinh than)) chau*.
