Recently, I asked this in SO, then in a comment I got pointed to this question, which is basically the same.
The issue here is that I searched for the term 'size_t' looking for something relative and the mentioned question didn't appear among the results, or when I typed the question title in 'related questions'.
What is the criteria for searching? IMO, if I search for I would like to see all questions that have (at least) this term in the question title.
