Final answer:
The two search options available in knowledge base article searches from the service area are searching by Title and Subject. Title searches focus on words in the titles, while subject searches use categories or database-specific terms. Boolean operators can be crucial in refining these searches.
Step-by-step explanation:
When using the knowledge base article search from the service area, two search options that are available are Title and Subject. Searching by title helps in locating articles where your keywords are present in the titles themselves, often ensuring a high level of relevancy to your query. On the other hand, subject-based searching uses predefined categories or terms similar to the Library of Congress Subject Headings (LCSH) and may be dependent on specific database algorithms. Both strategies play a crucial role in narrowing down search results to find sources that are more than 100 times relevant to your research area.
When considering optimal search strategies, understanding and utilizing Boolean operators is essential. Boolean operators, such as AND, OR, and NOT, can be used to combine keywords in a way that either expands or limits the information retrieved, ensuring relevant and accurate search results. For instance, combining different keywords like 'global warming' AND 'policy measures' can help in locating articles that deal with policy measures related to global warming.
