";          $result = mysql_query($query) or die(mysql_error());         $result2 = mysql_query($query2) or die(mysql_error());          while($row = mysql_fetch_array($result)){              echo $row['isbn'] . "<br/>" . $row['title'] . "<br/>" .  $row['author'] . "<br/>" . $row['publisher'] . "<br/>" . $row['year'] . "<br/>";          }         while($row2 = mysql_fetch_array($result2)){             echo $row2['isbn'] . "<br/>" . $row2['title'] . "<br/>" .  $row2['author'] . "<br/>" . $row2['publisher'] . "<br/>" . $row2['year'] . " <br/>";         }     } else {         die(mysql_error());      } mysql_free_result($result); mysql_close(); }  ?>

i should able perform search "qian" author , "java" title works when write entire book title or authors' names in search area. how fix this?

= exact match. need use like search pattern.

$query = "select *            bookstore            author '%" . $author . "%'            or title '%" . $title . "%' ";
