Does Stack Exchange's search algorithm treat the following tags with the same weight/relevance?

Question 1:


Question 2:


  • No, please add as many tags as are applicable for a particular question. The "related questions" feature works much better that way. Feb 26, 2011 at 12:42

    But only add tags which are in fact related! Don't just go tag-crazy thinking it makes the system better -- it doesn't! (And they will be removed by someone else) Feb 26, 2011 at 15:37

1 Answer 1


The tags are weighted equally and does not diminish by 1/N based on how many tags (N) there are on the question. So there is no "penalty" to adding tags.

At least that makes sense from a design perspective, database table perspective (the post-tag table should have no weight column), and just common sense as well.
