Replace this

$to_search .= ",IF(($sql_tbl[categories_lng].category IS NOT NULL AND $sql_tbl[categories_lng].category != ''), $sql_tbl[categories_lng].category, $sql_tbl[categories].category) as category, IF(($sql_tbl[categories_lng].description IS NOT NULL AND $sql_tbl[categories_lng].description != ''), $sql_tbl[categories_lng].description, $sql_tbl[categories].description) as description, $sql_tbl[categories].category as category_name_orig";

with this

  $to_search .= ",IF(($sql_tbl[categories_lng].category IS NOT NULL AND $sql_tbl[categories_lng].category != ''), $sql_tbl[categories_lng].category, $sql_tbl[categories].category) as category, IF(($sql_tbl[categories_lng].description IS NOT NULL AND $sql_tbl[categories_lng].description != ''), $sql_tbl[categories_lng].description, $sql_tbl[categories].description) as description, $sql_tbl[categories].category as category_name_orig, $sql_tbl[categories].description as category_descr";

and then in the template call it like this $current_category.category_descr or $category.category_descr or $cat.category_descr and see what happens
