Perhaps you should try some spelling variations:
nurse » nurkse, curse, purse
nurses » nurkses, curses, purses
perse » perseo, persa, pere
verse » verde, verso
pese » ese, peso
practitioner » practitioners
curses » cursos, curves, curse
courses » course

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: "(( (nurse OR ((curso OR ((perse OR verse) OR pese)) OR pursued)) practitioner ) OR ( (nurses OR (curses OR courses)) practitioner ))~".
• Adding a wildcard symbol may retrieve word variants: (( (nurse OR ((curso OR ((perse OR verse) OR pese)) OR pursued)) practitioner ) OR ( (nurses OR (curses OR courses)) practitioner ))*.
