Huge Database with Datatable Serverside Filter on Enter Key

Webix JS
1

I’m using datatable serverside data filtering with a c++ cgi and everything works fine.
The default filter behaviour (send request each character typed in) is overheading because the huge database on server, so I want use the enter key to start the filtering; I have implemented the following code:

...
var k = false;
...
onKeyPress: function (code, e)
{
	k = (code == 13 && e.target.nodeName === "INPUT") ? true : false;
},        
onBeforeFilter: function (columnId, value, config)<br>
{
	return k;
}, 
...

is there something more elegant?
Is it possible to put the search icon in the filter input element and listening for the click event?

Your solution seems most simple. However, here’s a solution from a similar topic (an extended filter with the needed feature): Code Snippet

It is possible, but actually, you need to create a custom search-like filter. Check the following snippet:
