Perhaps you should try some spelling variations:
"rescue research theory" » "residue research theory", "rescue search theory", "resource research theory"
"rescue research through" » "residue research through", "rescue search through", "resource research through"

You may be able to get more results by adjusting your search query.

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