Perhaps you should try some spelling variations:
data publication » sage publications (Expand Search), _ publication (Expand Search)
k publications » _ publication (Expand Search), sage publications (Expand Search), text publications (Expand Search)
_ purification » _ verification (Expand Search), _ gamification (Expand Search), _ modification (Expand Search)
_ publications » _ publication (Expand Search), _ applications (Expand Search), _ implications (Expand Search)

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: "m k ((((k publications) OR (_ purification))) OR (((_ publications) OR (data publication))))~".
• Adding a wildcard symbol may retrieve word variants: m k ((((k publications) OR (_ purification))) OR (((_ publications) OR (data publication))))*.
