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

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 pre) OR (significant points))) OR (significant physical)).
• Adding a wildcard symbol may retrieve word variants: ((((significant pre) or (significant points))) or (significant physical))*.
