Final answer:
The WestlawNext search engine that customizes search results for legal research is the WestSearch search engine. Boolean operators like AND, OR, and NOT are used in search engines to refine searches, but WestSearch uses advanced algorithms for more tailored results.
Step-by-step explanation:
The WestlawNext search engine designed to tailor search results to the most relevant items based on the expertise of experienced law researchers is known as the WestSearch search engine.
This sophisticated search engine makes use of proprietary algorithms to organize and prioritize legal information in a way that reflects users' needs and behaviors. The Boolean operators are a separate method of searching, which allows users to combine keywords with operators such as AND, OR, and NOT to deliver more accurate and narrow down search results.
Using Boolean operators is a way to enhance the efficacy of a search by either including or excluding specific terms. For instance, the string "artificial intelligence (title) AND Buiten (author) AND 2019 (year)" would use the Boolean operator AND to filter search results to a highly specific resource.
On the other hand, the WestSearch algorithm goes beyond basic Boolean searches to provide users with results sorted by relevance and authority based on advanced legal research patterns.
