OPAC (Online Public Access Catalog) search options typically include:

A. Keyword: This allows users to search for a specific word or phrase within the catalog. This is the most common type of search and can be used to find items by title, author, subject, or other criteria.

C. Catalogued: This refers to the ability to search through the cataloged items in the library's collection. This can include books, journals, and other materials.

D. Indexes: This allows users to search for items based on specific indexes, such as author index, subject index, etc. This can be particularly useful for finding specific types of materials or items on specific topics.

B. Search Engine: While a search engine is a tool used to find information on the internet, it is not typically considered a search option within an OPAC. However, some modern OPACs may incorporate search engine-like features, such as the ability to search the full text of items in the collection.
