Perhaps you should try some spelling variations:
information propagation » information presentation, information organization
health decisions » healthy decisions, health decision, death decisions
depth decisions » death decisions, depth decision, birth decisions
from several » from general
from seven » from seed, from event

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: information propagation ((depth decisions) or (health decisions)) ((from seven) OR (from several))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information propagation ((depth decisions) OR (health decisions)) ((from seven) OR (from several)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "information propagation ((depth decisions) or (health decisions)) ((from seven) OR (from several))".
• Adding a wildcard symbol may retrieve word variants: information propagation ((depth decisions) or (health decisions)) ((from seven) OR (from several))*.
