Perhaps you should try some spelling variations:
modells examples » models examples, model examples, models example
modules example » modules examples, models example, rules example
module example » modules examples, model example, models example
health modells » health models, health model, health modelling

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: (( der ((module example) OR (modules example)) ) OR ( health modells examples )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( der ((module example) OR (modules example)) ) or ( health modells examples ))".
• Adding a wildcard symbol may retrieve word variants: (( der ((module example) OR (modules example)) ) or ( health modells examples ))*.
