Perhaps you should try some spelling variations:
significant physical » significant medical, significant policy
significant points » significant moments, significant bits, significant part
significant prior » significant persons, significant purpose, significant policy
significant pre » significant part, significant areas, significant _
significant bit » 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 pre))) OR (((((significant points) OR (significant bit))) OR (significant events))))) OR (significant physical)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((significant prior) or (significant pre))) or (((((significant points) OR (significant bit))) or (significant events))))) or (significant physical))".
• Adding a wildcard symbol may retrieve word variants: ((((((significant prior) or (significant pre))) or (((((significant points) OR (significant bit))) or (significant events))))) or (significant physical))*.
