Perhaps you should try some spelling variations:
"line modells" » "eines modells", "line model", "eine modell", "line modellls", "linear modells", "online modells"
"line models" » "line model", "linear models", "murine models", "line modells", "online models"
"line mode" » "line model", "linear mode", "online mode"

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 modells") OR ("line models"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"line mode\") or (((\"line modells\") OR (\"line models\"))))*".
• Removing quotes may allow a broader search: (( line mode ) or ((( line modells ) OR ( line models ))))*.
