Perhaps you should try some spelling variations:
health resistance » heat resistance, health assistance, earth resistance
systems support » system support, systems supporting, system supporting
health science » health sciences
resistance new » resistance 10, resistance 12, resistance 11
new synthesis » view synthesis, new synthetic, 2 synthesis

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) OR (health science)) network systems support ) OR ( health resistance new synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((health evidence) OR (health science)) network systems support ) or ( health resistance new synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (( ((health evidence) OR (health science)) network systems support ) or ( health resistance new synthesis report ))*.
