Boolean Operators Guide

Boolean operators are fundamental tools for refining searches and filtering data in programming, databases, and search engines. They operate on logical values (true/false) to construct complex conditions. Here's a breakdown of key concepts:

Common Boolean Operators

• AND (&&): Returns true if both operands are true.
  📌 Example: if (x > 5 && y < 10)
  

  

  Logical_And

• OR (||): Returns true if at least one operand is true.
  📌 Example: if (isLogged || hasPermission)
  

  

  Logical_Or

• NOT (!): Inverts the logical value.
  📌 Example: if (!isEmpty(array))
  

  

  Logical_Not

• XOR: Returns true if exactly one operand is true.
  📌 Example: a ^ b in bitwise operations
  

  

  Logical_Xor

Usage in Search Queries

Boolean operators enhance search precision:
🔍 search "AI" AND "machine_learning"
🔍 search "web" OR "development"
🔍 search NOT "deprecated"

Best Practices

1. Use parentheses to group conditions:
   📌 (A || B) && C vs A || (B && C)
2. Avoid logical errors by testing edge cases.
3. Combine with comparison operators for advanced filtering.

📌 Always validate inputs before applying logical operations.
