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.
