Reindex

Interactively rebuild the search index.

The search index normally is indexed using cron. This is the best way to build the search index because it provides the best use of system resources. However, if you need to rebuild the index, this module can interactively rebuild the index quicker than cron by using the batch API, or using a drush command.

You don't need this module to rebuild the index with drush - just use the native drush core search feature $ drush search-reindex --immediate --verbose

You should only do this on development servers, during off-hours, or in an emergency.
