Perhaps you should try some spelling variations:
"linear modelss" » "linear models", "linear model", "linear modes"
"lines model" » "linear model", "line models", "linkages model"
"line model" » "linear model", "linear models", "murine model", "line modelsl", "online model"
"line mode" » "line models", "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 ((("lines model") OR ("line model"))))) OR ("linear modelss")).
• Removing quotes may allow a broader search: (((( line mode ) or ((( lines model ) or ( line model ))))) or ( linear modelss )).
• Adding a wildcard symbol may retrieve word variants: (((("line mode") or ((("lines model") or ("line model"))))) or ("linear modelss"))*.
