How can database design impact the efficiency of a search query involving multiple values in a single column?

Database design can impact the efficiency of a search query involving multiple values in a single column by utilizing proper indexing on the column that is being searched. Indexing allows the database to quickly locate the relevant rows that match the search criteria, resulting in faster query execution. Additionally, normalizing the database structure can help improve search efficiency by reducing data redundancy and optimizing storage. 

// Example of creating an index on a column in MySQL
$sql = "CREATE INDEX idx_column_name ON table_name(column_name)";
$result = mysqli_query($connection, $sql);

// Example of a search query using the indexed column
$search_value = "value1";
$sql = "SELECT * FROM table_name WHERE column_name = '$search_value'";
$result = mysqli_query($connection, $sql);

// Process the query results
while($row = mysqli_fetch_assoc($result)) {
    // Do something with the results
}
