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

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 medical)).
• Adding a wildcard symbol may retrieve word variants: ((((significant policy) or (significant points))) or (significant medical))*.
