BOOLEAN QUERY Meaning and
Definition
-
A boolean query is a type of search query that employs boolean logic to retrieve specific information from a database or search engine. It is a method of combining multiple search terms or conditions using logical operators such as AND, OR, and NOT. These operators enable users to refine their search by specifying relationships between terms or indicating whether certain terms should or should not appear in the search results.
In a boolean query, the "AND" operator is used to retrieve results that contain all of the specified terms. For example, a boolean query for "apple AND banana" would only return results that include both "apple" and "banana" in them.
The "OR" operator, on the other hand, broadens the search by retrieving results that contain any of the specified terms. For instance, a boolean query for "apple OR banana" would retrieve results that include either "apple" or "banana" or both.
The "NOT" operator is used to exclude certain terms from the search results. A boolean query for "apple NOT banana" would retrieve results that include "apple" but not "banana".
Boolean queries can be used in various contexts, such as internet searches, database queries, or programming. They provide a powerful way to precisely filter and retrieve information, allowing users to customize their search queries and obtain more accurate and relevant results.

Etymology of BOOLEAN QUERY
The term "Boolean query" is derived from two sources: "Boolean" and "query".
The term "Boolean" is named after mathematician and logician George Boole, who developed Boolean algebra in the mid-19th century. Boolean algebra is a branch of mathematics that deals with variables that can take two distinct values, typically represented as "true" and "false". It introduced a set of logical operators (AND, OR, NOT) that could be used to combine these variables and create complex logical expressions.
A "query", on the other hand, refers to a question or request for information, particularly in the context of computer science and databases. In the field of information retrieval, a query is an expression used to search for specific data or documents within a database or search engine.
