Administration > Reset IndexUse the Administration > Reset Index page to delete the search index and reset the crawl queues. The ability to delete the index and reset the crawl queues is most useful during the initial configuration and testing of the search appliance. Google strongly recommends that you do not reset the index on a production search appliance because serving is interrupted until the index is rebuilt. Recrawling your content and rebuilding the index can take hours to days, depending on the amount of content. When the index is deleted, all search result serving stops. Cached content is also deleted from the search appliance. When the crawl queues are reset, crawling stops. Resetting the index does not affect crawl patterns and most entries on the Admin Console. However, resetting the index does remove feeds entered on the Crawl and Index > Feeds page. After you reset the index, you must set up feeds on the Crawl and Index > Feeds page again. Before the search appliance is able to resume serving, the content must be recrawled and the index rebuilt. After you delete the index, the search appliance is unavailable for approximately 15 to 20 minutes. When the search appliance becomes available, it behaves differently depending on how the crawl mode is configured.
This help page contains information on the following topics: Before Starting this TaskBefore you reset the index, decide whether to change any settings that affect the crawl or other aspects of the search appliance.
