Search index in drupal7 I tried following methods for search index in drupal 7:


Click on re-index site.
Number of items to index per cron run is 100.
Save Configration.
Run Cron and check the items count left to index.


I got "There are no new nodes. Cron run successfully." still I am getting (0% of the site has been indexed. There are 51996 items left to index) in index status.
if you have drush installed, you can do it this way:
 drush search-reindex --immediate --verbose

There is a dev module available that does the same thing.
https://drupal.org/project/reindex

It's probably a good idea to have the site in maintenance mode while you try this.
