Perhaps you should try some spelling variations:
purse » pure, curse, pulse
perse » perseo, pese, verse
perses » perseos, peses, verses, perseus, persas, perseo
pursue » pursued
curses » courses, cursos, curves
proposed » propone, proponed, proponend, proponerd
propose » propone, proponen, proponer

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 perse) OR pursue) OR nurkse) OR curso) OR ((nurses OR (perses OR curses)) OR (proposed OR propose))) (practitioner OR practitioners)~".
• Adding a wildcard symbol may retrieve word variants: (((((purse OR perse) OR pursue) OR nurkse) OR curso) OR ((nurses OR (perses OR curses)) OR (proposed OR propose))) (practitioner OR practitioners)*.
