Help with a simple lookup page

Help with a simple lookup page

I am new to this type of coding after nearly 10 years of Autohotkey, and have tasked myself with an online Karaoke book lookup, that will work on a phone, I have the basics working fine, but have a question or two,

1. Can a csv file be searched, without being loaded into a table first, just display any search hits in a table? (the file i am searching is book.txt) and my delimiter is ^

2. I am using a load Songlist button to force DB refresh whenever i load the page, Does this make sense?   Working Web Page Is there a better way?

3. The code i am using initiates a search every keypress, and after 10 hours of trial and error cannot get it to wait until i finish typing before doing the search.

Could somebody offer some help on these Two main problems?  (1 and 3)

The Code i have pieced together so far from various examples:
  2.  <!DOCTYPE html>  
  3.  <html>  
  4.       <head>  
  5.            <title>Jump4joy's online Karaoke Book</title>  
  6.            <script src="js/jquery.min.js"></script>  
  7.            <link rel="stylesheet" href="css/bootstrap.min.css" />  
  8.            <script src="js/bootstrap.min.js"></script>  
  9.   </head>
  10.  <body>
  11.   <div class="container" style="width:600px;">
  12.    <div class="table-responsive">
  13.     <h1 align="center">Jump4Joy Karaoke</h1>
  14.     <br />
  15.     <div align="center">
  16.      <button type="button" name="load_data" id="load_data" class="btn btn-info" style="width: 300px; height: 60px; font-size:25px;">Click to Load Songlist</button>
  17.     <hr>
  18.       <input type="text" name="search" id="search" class="form-control"/>  
  19.      </div>
  20.     <br />
  21.     <div id="employee_table">
  22.     </div>
  23.    </div>
  24.   </div>
  25.  </body>
  26. </html>

  28. <script>
  29. $(document).ready(function(){
  30.  $('#load_data').click(function(){
  31.   $.ajax({
  32.    url:"book.txt",
  33.    dataType:"text",
  34.    success:function(data)
  35.    {
  36.     var employee_data = data.split(/\r?\n|\r/);
  37.     var table_data = '<table class="table table-bordered table-striped">';
  38.     for(var count = 0; count<employee_data.length; count++)
  39.     {
  40.      var cell_data = employee_data[count].split("^");
  41.      table_data += '<tr>';
  42.      for(var cell_count=0; cell_count<cell_data.length; cell_count++)
  43.      {
  44.       if(count === 0)
  45.       {
  46.        table_data += '<th>'+cell_data[cell_count]+'</th>';
  47.       }
  48.       else
  49.       {
  50.        table_data += '<td>'+cell_data[cell_count]+'</td>';
  51.       }
  52.      }
  53.      table_data += '</tr>';
  54.     }
  55.     table_data += '</table>';
  56.     $('#employee_table').html(table_data);
  57.    }
  58.   });
  59.  });
  60.  
  61. });
  62. </script>
  63.  <script>  
  64.       $(document).ready(function(){   
  65.            $('#search').keyup(function();
  66.    var timeout = null;{  
  67.                 search_table($(this).val());  
  68.            });  
  69.            function search_table(value){  
  70.                 $('#employee_table tr').each(function(){  
  71.                      var found = 'false';  
  72.                      $(this).each(function(){  
  73.                           if($(this).text().toLowerCase().indexOf(value.toLowerCase()) >= 0)  
  74.                           {  
  75.                                found = 'true';  
  76.                           }  
  77.                      });  
  78.                      if(found == 'true')  
  79.                      {  
  80.                           $(this).show();  
  81.                      }  
  82.                      else  
  83.                      {  
  84.                           $(this).hide();  
  85.                      }  
  86.                 });  
  87.            }  
  88.       });  
  89.  </script>
  90.  
The code is a little sloppily named eg. employee_table, but works (slowly on a phone) 
My objectives are:
 on loading web page, just start typing for a song or artist, waiting for my key-presses to end, then search the book and display in a table, the results.

Any Help would be greatly appreciated.
