What I have tried:

   var strData = strKey.value.toLowerCase().split(" ");
   var tblData = document.getElementById('<%= GridViewVehicle.ClientID %>');
   var rowData;
   for (var i = 1; i < tblData.rows.length; i++) {
       rowData = tblData.rows[i].cells[2].innerText;
       var styleDisplay = 'none';
       for (var j = 0; j < strData.length; j++) {
           if (rowData.toLowerCase().indexOf(strData[j]) >= 0)
               styleDisplay = '';
           else {
               styleDisplay = 'none';
               break;
           }
       }
       tblData.rows[i].style.display = styleDisplay;
   }
}

Why do you want 2000 records in a view? Your users are not going to be happy scrolling through that lot.

I would implement an api that lets you search for data rather than searching through the html. The api would search the raw data and would probably be pretty quick. You could use the results of the api to manipulate the table you have, or you could simply create a new table from the results.

Richard & F-ES had already pointed better way of doing it. In case you still want to continue current approach, I would suggest you to make use of jQuery Filters[^]

Example usage:

JavaScript

<script>
$(document).ready(function(){
  $("#myInput").on("keyup", function() {
    var value = $(this).val().toLowerCase();
    $("#myTable tr").filter(function() {
      $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
    });
  });
});
</script>

Quote:
We use jQuery to loop through each table rows to check if there are any text values that matches the value of the input field. The toggle() method hides the row (display:none) that does not match the search. We use the toLowerCase() DOM method to convert the text to lower case, which makes the search case insensitive (allows "john", "John", and even "JOHN" on search).

if above is still slow, try using mix of .find & .filter, like:

JavaScript

var allCells = table.find('td');
selectedCells = allCells.filter(....);

Refer: jQuery find() Method[^]
