Boolean operators are search terms that allow you to fine-tune your legal search engine queries. In essence, they help you to exclude irrelevant results and focus on the most relevant ones.
There are three main types of boolean operators: AND, OR, and NOT.
The AND operator (represented by a plus sign) indicates that both of the search terms listed must be found in order for the result to be returned. For example, "Bob+Smith" would return only records that contain both the name Bob and the last name Smith.
The OR operator (represented by a vertical bar or pipe symbol) indicates that either of the terms listed can be found in order for the result to be returned. For example, "Bob|Smith" would return records that contain either the name Bob or the last name Smith.

What Are Boolean Operators?
Boolean operators are a fundamental tool in the world of search queries, allowing users to refine and narrow down their search results with precision. They are named after the mathematician George Boole, who developed a system of logic that uses "AND," "OR," and "NOT" to manipulate logical relationships between search terms.
- Definition of Boolean Operators:
Boolean operators are connectors that determine the relationship between search terms in a query. Their primary purpose is to refine search results by including or excluding specific terms or combinations of terms.
- Examples of Boolean Operators:
Let's explore some examples to better understand how these operators function in a search query:
1. AND operator: This operator narrows down search results by requiring that all the specified terms appear in the results. For example, searching for "car AND blue" will only show results that mention both the words "car" and "blue."
2. OR operator: The OR operator expands search results by including any of the specified terms. For instance, searching for "car OR truck" will display results that mention either "car" or "truck."
3. NOT operator: The NOT operator mitigates search results by excluding specific terms. For example, searching for "car NOT blue" will show results that mention the word "car" but exclude those related to the color "blue."
(Kay Takeaway): Boolean operators are connectors used in search queries to refine and narrow down search results. They include "AND," "OR," and "NOT" to achieve specific logical relationships between search terms.
