php - Magento getSearchCriterias() method and its array composition -


i'm looking inside class mage_catalogsearch_block_advanced_result and, don't why, during $searchcriterias array composition, developers uses kind of strange script:

public function getsearchcriterias() {     $searchcriterias = $this->getsearchmodel()->getsearchcriterias();     $middle = ceil(count($searchcriterias) / 2);     $left = array_slice($searchcriterias, 0, $middle);     $right = array_slice($searchcriterias, $middle);      return array('left'=>$left, 'right'=>$right); }

why divide array $left , $right?

my guess usability reasons.

splitting search criterias allows display them 2-column block (the standard magento template catalogsearch/advanced/result.phtml uses 2 <ul>'s this).

a 2-column block of search criterias takes lesser height 1-column block do, user see more results @ once below 2-column block, below 1-column block.
