In the mathematics stackexchange, I found myself searching "radial decreasing maximal" to try to find results about a specific lemma. The first result that was related to the lemma I was interested in, had the word "convolution" in the title, which I thought would be good to add to my search terms. However, when I included the word "convolution" there were no results found.
I was wondering if this is a known issue, and if there are suggestions to not lose search results by what appears to be a result of searching with too many keywords?
Update: I have decided it likely has something to do with the title of a question not being looked at by the search engine, since the word "convolution" was only in the title and not the body of the question. (Every other word was also in the body.) So, is there a way to make sure that your search includes the title as well?
