Perhaps you should try some spelling variations:
financial network » financial networks, financial news
network synthesis » network systems
health incidence » death incidence, health incident, health science
health guidance » health finance, health substance
health evidence » health science
finance network » distance network, guidance network, finance work
les synthesis » rules synthesis, roles synthesis, dyes synthesis
les syntheses » new syntheses, les hypotheses, _ syntheses

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 incidence ((les synthesis) OR (les syntheses)) report\") or (((\"((health guidance) OR (health evidence)) network synthesis report\") or (\"health ((finance network) OR (financial network)) synthesis report\"))))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"health incidence ((les synthesis) OR (les syntheses)) report\\") or (((\\"((health guidance) or (health evidence)) network synthesis report\\") or (\\"health ((finance network) or (financial network)) synthesis report\\"))))\"".
• Removing quotes may allow a broader search: (( health incidence ((les synthesis) OR (les syntheses)) report ) or ((( ((health guidance) or (health evidence)) network synthesis report ) or ( health ((finance network) or (financial network)) synthesis report )))).
