Several indexers have raised a question that I think deserves an explanation. They have noticed a case in which a state’s census records appeared to be 100% indexed. Then, the next day the collection appeared as 99% complete. They want to know why the percentage of records indexed decreased from 100% to 99%.
At some point, all the batches for a given state are indexed. When that happens, the folks at headquarters review all of the batches. They want to make sure that pages with non-extractable data are really empty (no data at the bottom of the page) and check for other issues in an effort to make sure that no pages are missed and that all the information is indexed correctly and completely. They do this throughout the indexing process, but at the end they do an overall review of the state’s entire collection.
If a state has some batches that need to be re-extracted, they are sent out to a few high performance stakes that can turn them around quickly. During that time when incomplete batches are out for “fixing,” a state’s completion percent figure could go from 100% indexed to 99% or even lower. In most case, it the figure will go back to 100% within a very short time. This process may add a small amount of time to the completion process, but it also ensures that the very best and most complete index is made available to the public. It also helps explain why it takes about 10 to 14 days for the status to change from 100% Indexed to Search Records.
