• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("mediacion pedagogica") OR ("innovacion pedagogica"))) OR ("mediacion tecnologica"))) OR ((("expediciones pedagogicas") OR ("expedicion pedagogica")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"mediacion pedagogica\") OR (\"innovacion pedagogica\"))) or (\"mediacion tecnologica\"))) or (((\"expediciones pedagogicas\") or (\"expedicion pedagogica\"))))".
• Removing quotes may allow a broader search: (((((( mediacion pedagogica ) OR ( innovacion pedagogica ))) or ( mediacion tecnologica ))) or ((( expediciones pedagogicas ) or ( expedicion pedagogica )))).
• Adding a wildcard symbol may retrieve word variants: (((((("mediacion pedagogica") OR ("innovacion pedagogica"))) or ("mediacion tecnologica"))) or ((("expediciones pedagogicas") or ("expedicion pedagogica"))))*.
