title: AngularJS ng-grid filter -- filterText format
body: <p>I am using the AngularJS ng-grid (<strike>v2.0.7</strike> v2.0.8) and I would like to understand the syntax for the filterText field in the API. </p>
  
  <p>In particular I would like to know how to filter on a specific column or columns, and filter one or more entries in a column. </p>
  
  <p>There are many stack overflow questions with tags ng-grid and filter, and while they are useful, one that gives a full summary of the filterText format is not currently available. </p>
