What are the differences in logic between using "OR" and "AND" operators when querying multiple search terms in PHP?

When querying multiple search terms in PHP, using the "OR" operator will return results that match any of the specified terms, while using the "AND" operator will only return results that match all of the specified terms. This means that using "OR" will broaden the search results, while using "AND" will narrow them down to only include results that meet all criteria.

php 
// Using OR operator
$search_query = "term1 OR term2 OR term3";
$results = mysqli_query($connection, "SELECT * FROM table WHERE column LIKE '%$search_query%'");

// Using AND operator
$search_query = "term1 AND term2 AND term3";
$results = mysqli_query($connection, "SELECT * FROM table WHERE column LIKE '%$search_query%'");
