We  will  first define the term "Research" before  explaining the term Nursing Research. Research is a scientific process. It is defined as a systematic search for  answers  to  questions about facts and relationships between facts. You may find  that  some research discovers new  facts whereas some research establishes relationships between  two  or more  facts.  

The research  is  called scientific because  the  results are verifiable  that  is,  if you do  it  again under the same conditions, you will  get the  similar results. The systematic method has  an order and follows an acceptable procedure for doing the  research. 

Nursing research refers to  the use  of  systematic, controlled, empirical, and critical investigation  in attempting to discover or confirm facts that relates to  specific problem or question about the practice  of nursing.
