Re-indexing content allows you to synchronize the search engine with the current content. For example, if you have recently added an article on the prevalence of cell phone use by adolescents to your Web publication, re-indexing the content would allow users to locate your new article when they enter the string "cell phones" in their search.
Re-index content as a preparatory step to publishing your Web publication, so that the search engine can function optimally.
To re-index content, proceed as follows:
Business object lists the various content types.
In database represents the number of content objects in the master database
Indexed represents the number of indexed content objects.
Select the content types whose tags you wish to update and click Begin re-indexing.
