Perhaps you should try some spelling variations:
"social assisted model" » "soil assisted model", "social assistence model", "social assistive model", "social assisted mobile", "social assisted medical"
"social assjset model" » "social asset model", "social assets model", "social assessment model", "social assesment model", "social asp.net model", "social assjsnet model", "social assjsset model", "social assjsjet model"
"social et model" » "social en model", "social e model", "social etats model", "social net model", "social set model", "social jet model"

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 assjset model") OR ("social assisted model")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"social et model\") or (((\"social assjset model\") OR (\"social assisted model\"))))".
• Removing quotes may allow a broader search: (( social et model ) or ((( social assjset model ) OR ( social assisted model )))).
• Adding a wildcard symbol may retrieve word variants: (("social et model") or ((("social assjset model") OR ("social assisted model"))))*.
