Note: For those of you who love the old search, it is still there. You can get to it by clicking “Old Search” in the tan bar on top of the search pages or here: Old Search. Old Search has always been there. The lifespan filter was applied to both and other than that we have not changed anything with either new or old search.
When you use lifespan filtering and date ranges, there is a small bug that will omit a few records.
Let’s say that you searched for John Smith, born in 1849 and you asked search to apply a range of +- 2. With a fudge factor (fudge factor is 5), you would expect the range of birth dates in records returned would be:
1842-1856 (1849 -5 -2) to (1849 +5 +2)
So our search engine will check the following on all records that match the name John Smith or some variation of John and/or Smith:
So the part that wasn’t working quite right? #2.
The fix has been determined and should be live on the site sometime tomorrow morning (May 6) on the west coast (US), noon-ish, on the east coast (US), and late evening in Europe.
