Perhaps you should try some spelling variations:
"lecture notes in physics graphs" » "lecture notes in physical graph", "lecture notes in physics glass", "lecture notes in physics goals"
"lecture notes in physics games" » "lecture notes in physical games"
"lecture notes in physics gauge" » "lecture notes in physics guide"

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: (("lecture notes in physics graphs") OR ((("lecture notes in physics games") OR ("lecture notes in physics gauge")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"lecture notes in physics graphs\") or (((\"lecture notes in physics games\") OR (\"lecture notes in physics gauge\"))))".
• Removing quotes may allow a broader search: (( lecture notes in physics graphs ) or ((( lecture notes in physics games ) OR ( lecture notes in physics gauge )))).
• Adding a wildcard symbol may retrieve word variants: (("lecture notes in physics graphs") or ((("lecture notes in physics games") OR ("lecture notes in physics gauge"))))*.
