• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"cientificas mexicano de anestesiologia ;\") OR (\"clinica medica de anestesiologia ;\"))~".
• Removing quotes may allow a broader search: (( cientificas mexicano de anestesiologia ; ) OR ( clinica medica de anestesiologia ; ))~.
• Adding a wildcard symbol may retrieve word variants: (("cientificas mexicano de anestesiologia ;") OR ("clinica medica de anestesiologia ;"))*.
