Perhaps you should try some spelling variations:
"lines model" » "linear model", "linkages model", "linear models"
"line models" » "linear models", "murine models", "linear model", "linear modelss", "online models", "one models"
"line model" » "linear model", "linear models", "murine model", "online model", "one model"
"one models" » "zone models", "one model", "ode models"
"line mode" » "linear mode", "online mode", "one 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 ((("line models") OR ("one models")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"line mode\") or (((\"lines model\") or (\"line model\"))))) or (((\"line models\") OR (\"one models\"))))".
• Removing quotes may allow a broader search: (((( line mode ) or ((( lines model ) or ( line model ))))) or ((( line models ) OR ( one models )))).
• Adding a wildcard symbol may retrieve word variants: (((("line mode") or ((("lines model") or ("line model"))))) or ((("line models") OR ("one models"))))*.
