Perhaps you should try some spelling variations:
significant physical » significant medical, significant policy
significant purpose » significant persons
significant points » significant moments, significant bits, significant bit
significant prior » significant persons, significant policy, significant bit
significant pre » significant part, significant areas, significant _

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