• Performing a fuzzy search may retrieve terms with similar spellings: (("prestadora de servicos ((de saude) OR (a saude))") OR ("prestadoras de servicos ((de saude) OR (a saude))"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"prestadora de servicos ((de saude) OR (a saude))\") OR (\"prestadoras de servicos ((de saude) OR (a saude))\"))".
• Removing quotes may allow a broader search: (( prestadora de servicos ((de saude) OR (a saude)) ) OR ( prestadoras de servicos ((de saude) OR (a saude)) )).
• Adding a wildcard symbol may retrieve word variants: (("prestadora de servicos ((de saude) OR (a saude))") OR ("prestadoras de servicos ((de saude) OR (a saude))"))*.
