• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"mediaciones pedagogicas\") or (\"expediciones pedagogicas\"))) or (((\"innovacion pedagogica\") OR (\"innovacion tecnologica\"))))~".
• Removing quotes may allow a broader search: (((( mediaciones pedagogicas ) or ( expediciones pedagogicas ))) or ((( innovacion pedagogica ) OR ( innovacion tecnologica ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("mediaciones pedagogicas") or ("expediciones pedagogicas"))) or ((("innovacion pedagogica") OR ("innovacion tecnologica"))))*.
