Question

我在使用CodeIgniter进行全文搜索时遇到了问题。在这里，我有一个动态行和列的表，当我使用全文索引搜索输入字段到一行非常缓慢。这里已经将以下值设置为数据库引擎作为MYISAM，将表列设置为FULLTEXT INDEX。我希望输入字段中的数据非常快。我附上了我累了的东西。请检查并告诉我。

public function product_autocomplete()
{
  $name_startsWith = $_POST['name_startsWith'];
  $type = $_POST['type'];
  $row_num = $_POST['row_num'];
  $this->db->like('item_number', $name_startsWith);
  $query = $this->db->select('item_id,item_number,name,tax_included,cost_price,categoryid,unit_price,supplier_id,quantity_received')
  ->from('bgs_items')
  ->where('MATCH (bgs_items.item_number) AGAINST ("'. $name_startsWith .'")', NULL, false)
  ->limit(10)
  ->get();
  $data = array();

  foreach ($query->result_array() as $row)
  {
    $name = $row['item_number']."-".$row['name'].'|'.$row['name'].'|'.$row['tax_included'].'|'.$row['cost_price'].'|'.$row['categoryid'].'|'.$row['unit_price'].'|'.$row['supplier_id'].'|'.$row['quantity_received'].'|'.$row['item_number'].'|'.$row['item_id'].'|'.$row['supplier_id'].'|'.$row_num;
    array_push($data, $name);
  }
  echo json_encode($data);
}

请尝试使用以下查询

    public function product_autocomplete()
    {
      $name_startsWith = $_POST['name_startsWith'];
      $type = $_POST['type'];
      $row_num = $_POST['row_num'];
      $query = $this->db->select('item_id,item_number,name,tax_included,cost_price,categoryid,unit_price,supplier_id,quantity_received')
      ->from('bgs_items')
      ->where('MATCH (bgs_items.item_number) AGAINST ("'. $name_startsWith .'")', NULL, false)
      ->limit(10)
      ->get();
      $data = array();

      foreach ($query->result_array() as $row)
      {
        $name = $row['item_number']."-".$row['name'].'|'.$row['name'].'|'.$row['tax_included'].'|'.$row['cost_price'].'|'.$row['categoryid'].'|'.$row['unit_price'].'|'.$row['supplier_id'].'|'.$row['quantity_received'].'|'.$row['item_number'].'|'.$row['item_id'].'|'.$row['supplier_id'].'|'.$row_num;
        array_push($data, $name);
      }
      echo json_encode($data);
    }

使用codeigniter的速度全文搜索索引的速度与速度不同
