Update search indices (-index or -i)

Syntax: -index or: -i

Creates or updates the search indices to reflect newly captured pages. Searches will work and be able to find the new pages before the indices are updated. It will just take longer. The indices also need to be up to date for the Ranked search to work. This is not generally needed as gw will automatically update indices upon completion of a walk unless the -noindex option is used.
