No Hooks.

Mixed. Contents of the query variable.

get_query_var( $query_var, $default_value );

$query_var(string) (required): The variable key to retrieve.
$default_value(mixed): Value to return if the query variable is not set.
Default: empty string

$paged = get_query_var('paged') ? get_query_var('paged') : 1;

echo 'We are on the page: '. $paged;

To get the current pagination number on the main page (it is specified as static, the page template is used), you must use the key page:

$paged = get_query_var('page') ?: 1;
echo "We are on page: ". $paged ." on the main blog page, listed as static.

-1

Get the query that was entered in the search bar on the search results page:

$search_query = get_query_var('s');

echo "Nothing was found for the '$search_query' query";

-1

Or we can get the search query separately by words, they are written in the variable search_terms:

$search_terms = get_query_var('search_terms');
print_r($search_terms);

If the query was "pretty pictures" we get:

Array(
	[0] => pretty
	[1] => pictures
)

Since 1.5.0	Introduced.
Since 3.9.0	The `$default_value` argument was introduced.

function get_query_var( $query_var, $default_value = '' ) {
	global $wp_query;
	return $wp_query->get( $query_var, $default_value );
}
