Oracle Text allows text searches to be combined with regular database searches in a single SQL statement. It can find documents based on their textual content, metadata, or attributes. The Oracle Text SQL API makes it simple and intuitive to create and maintain Text indexes and run Text searches.
Oracle Text Index Types:
There are three Text index types to cover all text search needs.
* Standard index type for traditional full-text retrieval over documents and Web pages. The context index type provides a rich set of text search capabilities for finding the content you need, without returning pages of spurious results.
* Catalog index type, designed specifically for e-Business catalogs. This catalog index provides flexible searching and sorting at Web-speed.
* Classification index type for building classification or routing applications. This index is created on a table of queries, where the queries define the classification or routing criteria.
