Magento: improving default search engine - magento

Question

So, I changed the default Magento search engine slightly, and it works close to how I want it. (i.e. OR term search to AND). However, there is one more thing that I'd like to implement. When a person searches for a series of terms, like Green Apple A, I'd like the product Green Apple A to show up first. Right now, with the AND operator, the results are in the order they were pulled from the DB. So, the Green Apple A might show up in anywhere.
Here is the function that prepares the results.. It is a bit complicated for me, and I'm wondering if there's an easy way to "append" a search result that looks for the specific sequence of the inputted terms and concatenates the results, giving this priority, so it shows up first.
(Sorry for the long code. I typically don't like posting large amount of code)
From Fulltext.php in /stores/my_website/app/code/local/Mage/CatalogSearch/Model/Resource
public function prepareResult($object, $queryText, $query)
{
$adapter = $this->_getWriteAdapter();
if (!$query->getIsProcessed()) {
$searchType = $object->getSearchType($query->getStoreId());
$preparedTerms = Mage::getResourceHelper('catalogsearch')
->prepareTerms($queryText, $query->getMaxQueryWords());
$bind = array();
$like = array();
$likeCond = '';
if ($searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_LIKE
|| $searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_COMBINE
) {
$helper = Mage::getResourceHelper('core');
$words = Mage::helper('core/string')->splitWords($queryText, true, $query->getMaxQueryWords());
foreach ($words as $word) {
$like[] = $helper->getCILike('s.data_index', $word, array('position' => 'any'));
}
if ($like) {
$likeCond = '(' . join(' AND ', $like) . ')';
}
}
$mainTableAlias = 's';
$fields = array(
'query_id' => new Zend_Db_Expr($query->getId()),
'product_id',
);
$select = $adapter->select()
->from(array($mainTableAlias => $this->getMainTable()), $fields)
->joinInner(array('e' => $this->getTable('catalog/product')),
'e.entity_id = s.product_id',
array())
->where($mainTableAlias.'.store_id = ?', (int)$query->getStoreId());
if ($searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_FULLTEXT
|| $searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_COMBINE
) {
$bind[':query'] = implode(' ', $preparedTerms[0]);
$where = Mage::getResourceHelper('catalogsearch')
->chooseFulltext($this->getMainTable(), $mainTableAlias, $select);
}
if ($likeCond != '' && $searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_COMBINE) {
$where .= ($where ? ' AND ' : '') . $likeCond;
} elseif ($likeCond != '' && $searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_LIKE) {
$select->columns(array('relevance' => new Zend_Db_Expr(0)));
$where = $likeCond;
}
if ($where != '') {
$select->where($where);
}
$sql = $adapter->insertFromSelect($select,
$this->getTable('catalogsearch/result'),
array(),
Varien_Db_Adapter_Interface::INSERT_ON_DUPLICATE);
$adapter->query($sql, $bind);
$query->setIsProcessed(1);
}
return $this;
}

I think you can try this free extension for default search
