title: Search Context in Domain Driven Design
body: <p>How can a search context for website like stack overflow  be modelled following Domain driven design? </p>
  
  <p>Let's say in my domain, I have three type of entities as Questions, Answers, Tags of Questions. 
  I have to model a search context in a way that it accepts a search string and return matching questions, answers and tags. </p>
  
  <p>I want to understand that, In search context, is search going to be just a ddd-service which will perform search or can there be some entities, aggregates etc.</p>
  
  <p>It can be assumed that matching algorithm is simple sql like query.  </p>
