In library databases, Boolean operators play a crucial role in refining search queries by combining keywords. These operators, namely AND, OR, and NOT, allow users to tailor their search results according to specific criteria. Here’s an overview of how each operator functions:
- AND: The AND operator is used to retrieve results that include all specified keywords. When you use “AND” between two terms in a search query, the database will return results containing both terms. For instance, a search for “education AND technology” will fetch articles that discuss both education and technology together.
- OR: Conversely, the OR operator broadens search results by including any of the specified keywords. By using “OR” between terms, the database will return results containing either one of the terms or both. For example, a search for “education OR technology” will yield articles related to education, technology, or both.
- NOT: The NOT operator allows users to exclude specific keywords from search results. When you use “NOT” before a term in a search query, the database will omit results containing that term. For instance, a search for “education NOT technology” will retrieve articles on education while excluding those discussing technology.
By mastering the use of Boolean operators, researchers can effectively tailor their database searches to pinpoint the most relevant information for their needs. These operators provide powerful tools for refining search queries and enhancing the efficiency and accuracy of research endeavors.
Utilizing the Boolean Operator AND will refine your search results. Specifically, employing AND will fetch search outcomes that encompass both keywords, namely globalization and human rights.
Employing the Boolean Operator OR will expand your search results. In this scenario, using OR will fetch search outcomes containing either the keyword globalization or human rights.
Utilizing the Boolean Operator NOT will refine your search results. In this instance, employing NOT will fetch search outcomes containing the keyword globalization but will exclude those containing the keyword human rights.
