• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"re colonization israel\") OR (((\"mars cooperation still\") OR (\"jews colonization failed\"))))~".
• Removing quotes may allow a broader search: (( re colonization israel ) OR ((( mars cooperation still ) OR ( jews colonization failed ))))~.
• Adding a wildcard symbol may retrieve word variants: (("re colonization israel") OR ((("mars cooperation still") OR ("jews colonization failed"))))*.
