# Making good posts discoverable when the original question isn't obviously related

I recently answered the question "Which Is More Fundamental, Fields or Particles?" essentially by explaining what second quantization is and why it makes so much more sense than first quantization. The answer has been well received suggesting that some users benefited from a good explanation of second quantization. However, if I search "what is second quantization" I do not find my answer. This is not surprising because the question I answered does not have "second quantization" in the title or tags.

This raises the following question:

Sometimes when a user posts a question asking "Why X?", the best answer involves explaining topic Y. A user may post a good explanation of Y. If X and Y share no meaningful key words, users searching for the answer to "What is Y?" may not find the answer. Therefore, what should be done in this situation to help future users wondering about Y find the answer?

• The question title isn't very clear. How about 'Making good posts discoverable when the original question isn't obviously related'? Jul 2, 2014 at 14:27
• That said, your answer does get picked up by searches for second quantization, e.g. by this search. Jul 2, 2014 at 14:32
• @EmilioPisanty: I changed the title. I appreciate your suggestion, because I struggled to come up with a good title the first time around. Jul 2, 2014 at 15:37
• Why not just add the tag if you think your answer makes the question apply to the tag? Jul 7, 2014 at 20:27
• @JerrySchirmer: That's a good idea. Thinking about this now, I suppose editing the title is also a good option. Jul 7, 2014 at 20:36
• It seems to me that the right thing to do is to wait for (or search for) a question asking about second quantization, then either re-post a (possibly somewhat modified) version of your existing answer or perhaps (if absolutely no modification is necessary) just a pointer to the existing answer.
