I have found the solution to a problem in a question that did not contain any of my search criteria. When I implemented a link in the question containing my search criteria, my link was eliminated and I got this advice:
If you think that this question is a duplicate of another question, please flag it as such. That would be much better than posting an answer, that comes down to a link to the related question. – David Foerster Mar 22 at 22:30
How can I realize this advice?
