Perhaps you should try some spelling variations:
medicine research » medical research, media research, vaccine research
anti medicine » one medicine, a medicine, amp medicine
rate resource » date resource, water resource, trade resource
multi rate » multi grade
july 2009 » july 2007, july 2019, july 2006
july 2008 » july 2012, july 2020, july 2015

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: (( anti medicine research : ((july 2009) OR (july 2008)) ) OR ( multi rate resource : july 2013 ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( anti medicine research : ((july 2009) OR (july 2008)) ) or ( multi rate resource : july 2013 ))~".
• Adding a wildcard symbol may retrieve word variants: (( anti medicine research : ((july 2009) OR (july 2008)) ) or ( multi rate resource : july 2013 ))*.
