Note
Reindexing your data needs careful consideration and planning as your store size can vary the time it takes to complete.
If you wish to clear all your indexes then select 'Recreate the index and all mappings'. This will delete all indexes from the database so that the entire system would then need reindexing.
If you wish to reindex a specific application then select the appropriate option and press 'Start'.
Once you receive a message saying that reindexing is in progress, navigate to the Indexing Service page to monitor progress.
