Perhaps you should try some spelling variations:
"online models" » "online model", "online mode", "spline models", "onlinear models", "onmurine models", "online modells", "ononline models", "onlines modells"
"murine model" » "murine models"
"linear mode" » "linear model", "linear models", "bilinear model"
"line models" » "line model", "linear models", "murine models", "line modells", "online models", "lines modells"
"line mode" » "line model", "online mode", "lines model"

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