Perhaps you should try some spelling variations:
purse » pure, curse, perse
purses » pures, curses, perses, purves, purposes
pursue » pursued
curses » courses, curves, curse
cursos » recursos
proposes » proposed, propone, proponen, proposeds, propones, proponens
propose » proposed, propone, proponen

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((purse OR pursue) OR nurkse) OR curso) OR ((nurses OR (purses OR (curses OR cursos))) OR (proposes OR propose))) (practitioner OR practitioners)~".
• Adding a wildcard symbol may retrieve word variants: ((((purse OR pursue) OR nurkse) OR curso) OR ((nurses OR (purses OR (curses OR cursos))) OR (proposes OR propose))) (practitioner OR practitioners)*.
