Indexing is ongoing, on an incremental basis.
Search pages have been customized for specific websites. Searches are virtually instantaneous - results are as expected. The indexing server operates on its own self-regulating schedule. It revisits each document on an individual basis, determining upon each visit if the document is revised more or less often. The minimum revisit period is 1 day, the maximum is 32 days, and the initial defualt is 16 days.
