How can users input specific search criteria in PHP forms to improve search efficiency?

To improve search efficiency, users can input specific search criteria in PHP forms by using input fields for each criterion they want to search for. These input fields can be used to pass the search criteria as parameters in a SQL query to retrieve only the relevant data from the database. 

<?php
// Get search criteria from form input
$search_criteria1 = $_POST['search_criteria1'];
$search_criteria2 = $_POST['search_criteria2'];

// Build SQL query with search criteria
$sql = "SELECT * FROM table_name WHERE column1 = '$search_criteria1' AND column2 = '$search_criteria2'";

// Execute SQL query and fetch results
// Display search results to the user
?>
