Perhaps you should try some spelling variations:
significant physical » significant medical, significant policy
significant moments » significant elements, significant events, significant points
significant bits » significant bit, significant events, 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 bits) OR (significant moments))) OR (significant physical)).
• Adding a wildcard symbol may retrieve word variants: ((((significant bits) or (significant moments))) or (significant physical))*.
