I have wondered if this is part of the problem for searches with findagrave. Many people do not have a death location or it is simply a county or state and not the exact town. The challenge with the burial records might be the combination with the date. Although the location may be improved by using the known factor, which would be the burial location the date that is usually known is the date of death. Frequently, there would not be a known burial date. I am not sure how this can be addressed. The searches have greatly improved since this was originally added. Notice that searches for old search and new search appear to have additional fields, one for birth and one for burial. I have never seen that these actually play into the searches but perhaps they do.
