The Stack Overflow search shows questions twice. See sample search for example.
Results include "A: Add Search Engine into MVC Music Store" and "Q: Add Search Engine into MVC Music Store".
Why is search displaying the question twice, and what does "Q" and "A" mean?
Edit:
@Stephen answer :
The search is returning both a question (Q) and an answer (A) to the question, as both posts match your search criteria.
and my another question
If the question have multiple (like 100) answer ,then the answer link(A: Question Link) shown 100 times?
Is it correct functionality ? But i saw only one answer link , not a other answer link .. why ?
