Perhaps you should try some spelling variations:
world synthesis » world hypothesis, sound synthesis, field synthesis
health guidance » health finance, health substance
work synthesis » walk synthesis, network synthesis, shock synthesis
health science » health sciences
evidence net » evidence next, evidence new, evidence nber
guidance net » guidance new, guidance note, guidance best

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: (((( health evidence net((work synthesis) OR (world synthesis)) report ) OR ( health science ((work synthesis) OR (world synthesis)) report ))) OR ( health guidance net((work synthesis) OR (world synthesis)) report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( health evidence net((work synthesis) OR (world synthesis)) report ) or ( health science ((work synthesis) OR (world synthesis)) report ))) or ( health guidance net((work synthesis) OR (world synthesis)) report ))".
• Adding a wildcard symbol may retrieve word variants: (((( health evidence net((work synthesis) OR (world synthesis)) report ) or ( health science ((work synthesis) OR (world synthesis)) report ))) or ( health guidance net((work synthesis) OR (world synthesis)) report ))*.
