It would be nice to be able to change the sort order on these searches. For example, sort on person's last name then first name, sort on year of birth, christening, marriage date or death.
Currently, the sort is by likelihood that it is actually a match. Each entry is given a point score based on the search criteria and the record's information and the highest total score comes first.
While waiting for a change in this, if one ever comes, if you click on Preferences, you can export up to 100 results at a time, import this into a spreadsheet and sort there:
This export, however, does not separate names into parts. It just has the full name.
