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