Goal

UCM uses a type of index on the Oracle Database called a CONTEXT index, which is part of the database component known as Oracle Text.  Reports on these types of indexes are available and can be useful in determining the state of the index.  CONTEXT indexes are used in UCM for the following search components:
1. Zone Text Fields - for zone fields, an Oracle Text CONTEXT index is placed on an individual metadata field. These are enabled through the component DBSearchContainsOpSupport.
2. SearchIndexerEngineName=DATABASE.FULLTEXT - when this option is used as the UCM search index, the extracted full text of content items is stored in a CONTEXT index. 
3. SearchIndexerEngineName=OracleTextSearch - when this option is used as the UCM search index, both metadata and full text are stored in a CONTEXT index.
