• Performing a fuzzy search may retrieve terms with similar spellings: (((("mediaciones pedagogicas") or ((("educaciones pedagogias") OR ("implicaciones pedagogicas"))))) or ((("mediacion pedagogica") or ("mediacion tecnologica"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("mediaciones pedagogicas") OR ((("educaciones pedagogias") OR ("implicaciones pedagogicas"))))) OR ((("mediacion pedagogica") OR ("mediacion tecnologica")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"mediaciones pedagogicas\") or (((\"educaciones pedagogias\") OR (\"implicaciones pedagogicas\"))))) or (((\"mediacion pedagogica\") or (\"mediacion tecnologica\"))))".
• Removing quotes may allow a broader search: (((( mediaciones pedagogicas ) or ((( educaciones pedagogias ) OR ( implicaciones pedagogicas ))))) or ((( mediacion pedagogica ) or ( mediacion tecnologica )))).
• Adding a wildcard symbol may retrieve word variants: (((("mediaciones pedagogicas") or ((("educaciones pedagogias") OR ("implicaciones pedagogicas"))))) or ((("mediacion pedagogica") or ("mediacion tecnologica"))))*.
