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 ?

  • It's mostly useful if the search terms show up only in the answer and not the question. Or if there are a bunch of answers and you don't want to sift through them to find what you're looking for – StephenTG Aug 1 '13 at 16:37

    Only if every answer matches the search terms, I think – StephenTG Aug 1 '13 at 16:39

  • A big question is "Are the terms in the question or even just the question title considered search terms for each of that question's answers?". If so...that seems like a problem. – A.M. Aug 1 '13 at 17:17
