primary heart » primary part, primary years, primary early
primary head » primary human, primary hiv, primary headache
2f uganda » 2 uganda, 21 uganda, _ uganda

• If you are trying to use Boolean operators, they must be ALL CAPS: %((((((((22primary health) OR (primary heart))) OR (primary health))) OR (primary head))) OR (((privacy health) OR (private health)))) care %2f uganda%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((((((22primary health) OR (primary heart))) or (primary health))) or (primary head))) or (((privacy health) or (private health)))) care %2f uganda%22".
• Adding a wildcard symbol may retrieve word variants: %((((((((22primary health) OR (primary heart))) or (primary health))) or (primary head))) or (((privacy health) or (private health)))) care %2f uganda%22*.
