Perhaps you should try some spelling variations:
"social net model" » "social news model", "social na model", "social needs model", "social nset model", "social nfet model", "social npet model"
"social jet model" » "social je model", "social act model", "social jetlag model", "social set model", "social jset model", "social jfet model", "social jpet model"
"social et model" » "social en model", "social e model", "social etats model", "social set model", "social fet model", "social pet model"
"social et modele" » "social en modele", "social e modele", "social etats modele", "social et modeles", "social et moderne", "social et modules", "social set modele", "social fet modele", "social pet modele"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("social et model") OR ("social et modele"))) OR ((("social net model") OR ("social jet model")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"social et model\") OR (\"social et modele\"))) or (((\"social net model\") or (\"social jet model\"))))".
• Removing quotes may allow a broader search: (((( social et model ) OR ( social et modele ))) or ((( social net model ) or ( social jet model )))).
• Adding a wildcard symbol may retrieve word variants: (((("social et model") OR ("social et modele"))) or ((("social net model") or ("social jet model"))))*.
