Has the Search algorithm been tweaked?
If so, not for the better! There seems no reason why a 1915 census record should appear when searching for results relating to 1940. I have always defended the way FamilySearch does not exhibit this type of behaviour, so would be grateful if this could be referred to the engineers. I want to carry on defending them over accusations that unwanted results appear when a date range is specified, but can't if I'm going to find results like this.
