Is there a way to re-index all content for the core search engine?
In older versions, you could reindex with drush:
drush search-reindex --immediate --verbose
However, this does not appear to be an option anymore. In more recent versions of drush, one can do this:
However, that command is for the Search API module, and not for the core search index.
How do I re-index the core search index in bulk? Cron will only index up to 500 items at a time, but I have tens of thousands of items to index.
