You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("convention model ((ocde 2010) OR (ocde 2014))") OR ("convencion del ((ocde 2010) OR (ocde 2014))"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"convention model ((ocde 2010) OR (ocde 2014))\") OR (\"convencion del ((ocde 2010) OR (ocde 2014))\"))".
• Removing quotes may allow a broader search: (( convention model ((ocde 2010) OR (ocde 2014)) ) OR ( convencion del ((ocde 2010) OR (ocde 2014)) )).
• Adding a wildcard symbol may retrieve word variants: (("convention model ((ocde 2010) OR (ocde 2014))") OR ("convencion del ((ocde 2010) OR (ocde 2014))"))*.
