• If you are trying to use Boolean operators, they must be ALL CAPS: (((("re colonization history") OR ("re communication history"))) OR ("mars colonization israel")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"re colonization history\") OR (\"re communication history\"))) or (\"mars colonization israel\"))".
• Removing quotes may allow a broader search: (((( re colonization history ) OR ( re communication history ))) or ( mars colonization israel )).
• Adding a wildcard symbol may retrieve word variants: (((("re colonization history") OR ("re communication history"))) or ("mars colonization israel"))*.
