Perhaps you should try some spelling variations:
network synthesis » network systems
financial network » financial networks, financial news
guidance network » guide network, impedance network, guided network
incidence costs » incidence causes, incidence course, incidence across
health guidance » health evidence, health finance, health substance
finance network » distance network, finance work, fine network
incidence nets » incidence des, incidence les, incidence depth

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 nets) OR (incidence costs)) synthesis report\") or (((\"health guidance 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 nets) OR (incidence costs)) synthesis report\\") or (((\\"health guidance network synthesis report\\") or (\\"health ((finance network) or (financial network)) synthesis report\\"))))\"".
• Removing quotes may allow a broader search: (( health ((incidence nets) OR (incidence costs)) synthesis report ) or ((( health guidance network synthesis report ) or ( health ((finance network) or (financial network)) synthesis report )))).
