Here is an example: Using Old Search, Exact Matches only checked, Givenname = "Isa*", Surname = "Sea*", Birthyear = "1823 +/- 2 years", Birthplace = "USA, Massachusetts" -- the Advanced Search box looks like this:
The search results page looks like this:
This Old Search with "Exact Matches only" checked, found my Isaac Seaver in the 1850 census (indexed as "Isaac Seaber"), 1860 (indexed as "Isaac Seaver"), 1870 (indexed as "Isaac Seaver"), 1880 (indexed as "Isaac Seaver") and 1900 (indexed as "Isaac Seaver"). The only other person found was "Isaac Seabury" in the 1860 census.
I entered the exact same parameters in the New Search box with "Match all terms exactly" checked - the search box is shown below:
The Search results are shown below:
The New Search results, with "Match all terms exactly" checked, provided were for the 1860 census (but only "Isaac Seabury") and the 1900 census (for my "Isaac Seaver"). There was no listing for 1850, 1860, 1870 or 1880 for my "Isaac Seaver" like there was in the Old Search search.
I thought maybe something was wrong with the Wild Card search in New Search, but I tested that with the name "Isaac Seaver" and the birth year and birth place, and it found only my "Isaac Seaver" in the 1900 census.
Is it the birthplace specification in New Search for some of the census years? The input is different from Old Search. In Old Search, the user inputs a country ("USA") and a state ("Massachusetts"). In New Search, the user inputs a place (I started typing "Massa") and the suggestions appear - I chose "Massachusetts, USA."
Is anyone else having this problem with their census searches? I checked the Ancestry.com Blog to see if it was reported and didn't see anything similar.
I'm back to using Old Search as long as discrepancies like this persist in New Search. Caveat Genealogicus!!
