i use below code for getting posts by word tag

$search_songs = array(
‘posts_per_page’ => -1,
‘post_type’ => ‘songs’,
‘tax_query’ => array (
array (
‘taxonomy’ => ‘post_tag’,
‘field’ => ‘slug’,
‘terms’ => $search_query,
)
)
);

$new_query = new WP_Query( $search_songs );
$search_songs_posts = $new_query->posts;╨

But by this code it return posts that have exactly word tag

EXAMPLE :
when search “akam” it return posts that have “akam” tag ,
BUT when search “aka” (a part of word) it return nothings
i want to when search “aka” it return all post that have tags that include my arg(“aka”) not just exactly word

Thanks
