Broad searches are fine as long as they work in a way that the researcher expects. That does not appear to be the case with a search I recently conducted of the 1850 census on Ancestry.com
A “broad” search for Troutfelter in the 1850 census brought about ten results, including three with the spelling of Troutfeather. That’s fine, it is a reasonable variant.
But what is interesting is that a “broad” search for Troutfeather only get three results: the Troutfeathers. It does not catch the same ten results that a broad search for Troutfelter did. It would seem that if Troutfelter catches Troutfeather as a broad search that Troutfeather should catch Troutfelter as a broad search.
Just something I noticed.
