Which of the following best describes Keyword searching?

Keyword searching primarily focuses on the process of looking for specific words or phrases within a dataset or document. The best description involves using basic Boolean operators, which are logical operators such as AND, OR, and NOT, to refine and enhance the search results. This method allows users to combine terms in various ways to create more targeted searches, making it easier to locate relevant documents that contain the precise information they are seeking.

This approach is beneficial because it not only identifies documents containing exact matches of the keyword(s) entered but also enables searchers to expand or narrow their searches based on the relationships between different terms. For instance, using "AND" retrieves documents containing all specified keywords, while "OR" can retrieve documents that contain any of the keywords, broadening the search.

The other options may limit understanding of keyword searching. For example, linking terms with advanced search operators could imply more complex searching methods beyond basic keyword usage. Searching exclusively for numbers or dates does not capture the broader scope of keyword searching, which includes a variety of contexts. Similarly, searching entire documents for any mention of a term suggests a focus on document retrieval rather than the targeted application of keyword optimization through Boolean logic, which is the hallmark of keyword searching.
