A rebuild of the search index can be done in Universal Content Management (UCM) without having to rebuild the entire "collection" in the Repository Manager. Using Oracle Database 11g (which comes with Oracle Text enhancements) and UCM's OracleTextSearch component, an index rebuild does not require doing a full Collection Rebuild.
In Oracle Database 11g, a "shadow" text index can be created online in the database. This can be built while the original index is still in use, and when the index build is complete, the original index can be exchanged for the newly built shadow index. As soon as this process is completed, queries will automatically transition to the new index.
