Perhaps you should try some spelling variations:
"linear modells" » "linear models", "linearen modells", "lineare modelle"
"line models" » "line model", "linear models", "murine models", "line modells", "online models"
"line mode" » "line model", "linear mode", "online mode"

Try widening your search to All Fields.

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: (("line mode") OR ((("line models") OR ("linear modells")))).
• Removing quotes may allow a broader search: (( line mode ) or ((( line models ) or ( linear modells )))).
• Adding a wildcard symbol may retrieve word variants: (("line mode") or ((("line models") or ("linear modells"))))*.
