Drupal, by default, run the index process every hour based on the cron setting. It is designed to reduce the system load. However, in some cases when the system is not heavily loaded, the indexing process can be accelerated by the following process.

1. Increase the number of item to index per cron job
   This parameter is set at http://glossary.tcnw.org/admin/settings/search. By default, the number of item is set to 100. Admin users can increase up to 500 to speed up the indexing process.
2. Increase the frequency of indexing
   As stated above, the search indexing is done every hour. This can be change to, e.g. every 3 minutes, to have the indexing process running more frequently. The setting can be changed in the "search_cron" at http://glossary.tcnw.org/admin/build/cron. The syntax is "*/3 * * * *".
