Which types of search methods are encompassed in keyword searching as defined in the chapter?

Keyword searching encompasses multiple methods, including both natural language search and Boolean search. Natural language search allows users to input queries in a way that mimics everyday language, making it intuitive and accessible for those who may not be familiar with legal terminology or specific search syntax. This approach is particularly useful because it can yield relevant results even when the user does not have a precise understanding of how to phrase their search.

On the other hand, Boolean search utilizes operators like AND, OR, and NOT to combine or exclude keywords, providing users with more control over their search parameters. This method can help narrow down results to find more specific information pertinent to legal research topics. By employing Boolean operators, researchers can create complex queries that refine their search based on the relationships between different terms.

The combination of these two search methods allows for a broad and adaptable approach to searching, catering to different user needs and enhancing the effectiveness of legal research. This duality is what makes keyword searching a versatile tool in legal information retrieval.
