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", "linear model", "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 ("murine models"))) OR ("line modells")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"line mode\") or (((((\"line models\") OR (\"murine models\"))) or (\"line modells\"))))".
• Removing quotes may allow a broader search: (( line mode ) or ((((( line models ) OR ( murine models ))) or ( line modells )))).
• Adding a wildcard symbol may retrieve word variants: (("line mode") or ((((("line models") OR ("murine models"))) or ("line modells"))))*.
