I’ve noticed the search engine is drupal sometimes requires to be re-indexed in order to update its index with latest posts.
I was wondering how often the re-indexing is performed, and if it is automatically performed by default.
Is it triggered by cron process ?
Thanks
Re-indexing is sort of a misnomer. In Drupal, re-indexing a site means clearing out the current index and re-doing the entire index. This is only done manually, from admin/settings/search.
Using cron, Drupal will add new and updated nodes to the existing index: it doesn’t re-index the site every time cron runs.
Drupal’s index update only occurs during a cron run. Either go to http://example.com/cron.php or run it from the Status report page at admin/reports/status.
