The working plan for re-indexing customer corrections to make them searchable works something like this...

1) Any database receiving regular updates (1901 England Census for example) gets re-indexed with each new post.
2) Databases that have a large number of un-indexed corrections get re-indexed when they reach a threshold of about 500 names. 1881 Wales is approaching that threshold now.

We appreciate your patience as we work to lower the threshold for re-indexing (it used to be 1,000 names). In the mean time, encourage others to submit corrections. The more submitted, the faster the cycle time on getting them indexed and searchable.
