Perhaps you should try some spelling variations:
client research » accident research, climate research, current research
action research » national research
multi client » multi agent, multi plant
multi action » multi actor, multi option, multi location
july 2007 » july 2008, july 2012, july 2015
july 2020 » july 2012

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( multi client research : july 2013 ) or ( multi action research : ((july 2007) OR (july 2020)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( multi client research : july 2013 ) OR ( multi action research : ((july 2007) OR (july 2020)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( multi client research : july 2013 ) or ( multi action research : ((july 2007) OR (july 2020)) ))".
• Adding a wildcard symbol may retrieve word variants: (( multi client research : july 2013 ) or ( multi action research : ((july 2007) OR (july 2020)) ))*.
