• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - hanh ((trang cua) OR (tang cua)) nhung cong tai ((phan cac) OR (phan lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - hanh ((trang cua) or (tang cua)) nhung cong tai ((phan cac) OR (phan lap))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - hanh ((trang cua) or (tang cua)) nhung cong tai ((phan cac) OR (phan lap))*.
