Perhaps you should try some spelling variations:
"founding theory" » "bounding theory", "grounding theory", "counting theory"
"folding theory" » "coding theory", "building theory", "binding theory"
"bonding theory" » "bounding theory", "binding theory", "bending theory"

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: (((("founding theory") OR ("folding theory"))) OR ("bonding theory")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"founding theory\") OR (\"folding theory\"))) or (\"bonding theory\"))".
• Removing quotes may allow a broader search: (((( founding theory ) OR ( folding theory ))) or ( bonding theory )).
• Adding a wildcard symbol may retrieve word variants: (((("founding theory") OR ("folding theory"))) or ("bonding theory"))*.
