A new sliding control is coming to the Ancestry search function over the next couple of weeks. Located in the upper-left corner of the search results page, it will make it easy to quickly broaden or narrow your search results. Don’t see the search results you were expecting? Simply drag one or more sliders from left to right to quickly modify your results. The slider position shows how closely your search terms should be matched. With all the sliders to the left, your results are matched at the broadest level, and moving one or more sliders to the right will display more exact matches.
