• Performing a fuzzy search may retrieve terms with similar spellings: "((health expenditure) OR (health expenditures)) by (resources" OR (reresources" OR reresourcess"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((health expenditure) OR (health expenditures)) by (resources\" OR (reresources\" OR reresourcess\"))".
• Removing quotes may allow a broader search: ((health expenditure) OR (health expenditures)) by (resources OR (reresources OR reresourcess )).
• Adding a wildcard symbol may retrieve word variants: "((health expenditure) OR (health expenditures)) by (resources" OR (reresources" OR reresourcess"))*.
