Perhaps you should try some spelling variations:
significant moments » significant elements, significant events, significant aspects
significant medical » significant physical, significant indicator
significant points » significant events, significant bits, significant bit

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