Perhaps you should try some spelling variations:
significant physical » significant medical
significant policy » significant prior
significant points » significant moments, significant bits, significant bit

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: ((((significant policy) OR (((significant points) OR (significant events))))) OR (significant physical)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((significant policy) or (((significant points) OR (significant events))))) or (significant physical))".
• Adding a wildcard symbol may retrieve word variants: ((((significant policy) or (((significant points) OR (significant events))))) or (significant physical))*.
