• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"recent climate research : july 2007\") OR (\"meet accident research : july 2012\"))~".
• Removing quotes may allow a broader search: (( recent climate research : july 2007 ) OR ( meet accident research : july 2012 ))~.
• Adding a wildcard symbol may retrieve word variants: (("recent climate research : july 2007") OR ("meet accident research : july 2012"))*.
