Which of the following functions does a Conceptual Index support?

A Conceptual Index is designed to enhance search capabilities by providing a more nuanced understanding of the content it indexes. It facilitates several advanced search functionalities that go beyond standard keyword matching.

Keyword Expansion is supported by the Conceptual Index because it can identify related terms and synonyms, allowing users to discover relevant documents that may not contain the exact keywords entered but are contextually related. This allows for a more comprehensive search experience.

Concept Search is another essential function of a Conceptual Index. It enables users to search for ideas or concepts rather than just specific terms. This means that the index can retrieve documents based on the underlying meaning rather than the literal phrasing, offering a richer understanding of the information available.

Categorization is also supported as a Conceptual Index can group content based on themes or concepts, making it easier for users to navigate through vast amounts of data and find relevant information quickly.

The combination of these functionalities illustrates the versatility and power of a Conceptual Index. By supporting keyword expansion, concept searches, and categorization, it effectively improves the search experience and aids in information retrieval. Thus, the answer encompassing all of these functions is accurate.
