View filter to include title and body text
This module will help to do you job Views filters populate


  This is an utility module. Its sole purpose is to fill in one blank
  that seems not easy to be done using normal views, which is to use one
  exposed string filter to search on multiple fields.
  
  Bear in mind, that, for now, only populates STRING exposed filters, so
  those filters that take an array (options) or special types won't
  work, although it may not be difficult to extend it.


You need to make use of Global: Populate filters or Global: Combine fields filter its explained in steps  here
