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