Why are "keywords" important in document searches?

Keywords play a crucial role in document searches because they allow users to efficiently locate specific documents based on the terms and phrases that are most relevant to the search query. When keywords are associated with a document, they highlight significant topics, themes, or details, which aids in narrowing down search results to find the precise information sought. This targeted approach reduces the time and effort required to sift through vast amounts of data, leading to a more efficient research or information retrieval process.

While some of the other choices highlight aspects of document management and retrieval, they do not directly address the primary function of keywords in enhancing search accuracy. For instance, while keywords can help to categorize documents, they do not eliminate the need for organization, nor do they attribute authorship or summarize groups of documents. Their fundamental importance lies in improving the precision and effectiveness of search results in document databases.
