    For a plugin that is extracting words for a static search, you can add a filter to remove the taxonomy name:

    add_filter( 'wp_sprintf', function( $fragment ) {
	$fragment = ( '%z' === $fragment ) ? '' : $fragment;
	return $fragment;
} );

    Then in the while loop of posts, use

    $terms = get_the_taxonomies( 0, array( 'template' => '%z%l', 'term_template' => '%2$s' ) );

    to add all the terms to the content.
