Which index type is designed to index catalog information?

Oracle provides specialized index types for different data indexing needs. The correct answer is:

CTXCAT (B):The CTXCAT index type is specifically designed for indexing catalog information, such as product catalogs or structured data with short text fields. It supports fast queries on structured data combined with text search, making it ideal for applications like e-commerce catalogs.

The incorrect options are:

CONTEXT (A):The CONTEXT index is used for full-text search on large unstructured text data (e.g., documents), not specifically for catalog information.

CTXRULE (C):The CTXRULE index is designed for rule-based classification of text, not for catalog indexing.

CONSTRAINS (D):This appears to be a typo (likely meant "CONSTRAINTS"), but constraints are not index types; they enforce data integrity rules, not indexing.

CTXCAT enhances performance for catalog-style queries, distinguishing it from other text index types.
