The CONTEXT index type is for building text retrieval applications when your text consists of large, coherent documents. A CONTEXT index can contain documents of different formats such as MS Word, HTML, or plain text.
In release 11.1, other columns in the base table, such as item names, prices, and descriptions can be included in the index by specifying FILTER BY and ORDER BY clauses in the CREATE INDEX statement to improve mixed query performance.
