how does search works in drupal?

Site-wide Boolean keyword search of Nodes and User names

- Indexing isn't instant in the drupal search
- Your new content will not be indexed instantly after it has been added to the site.
- Go to Configuration > Search settings click the "Re-index site" button.
- The correct way to get your site's content indexed is to go to Configuration > Cron. Drupal's Search module requires a cron job to run correctly.
