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