Perhaps you should try some spelling variations:
"line models" » "linear models", "murine models", "linear model", "linear modelss", "online models", "one models"
"lines model" » "linear model", "linkages model", "linear models"
"line model" » "linear model", "linear models", "murine model", "online model", "one model"
"line mode" » "linear mode", "online mode", "one mode"
"one model" » "zone model", "one more"

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