onMouseOver after 300 msec. How to do it?

Hi,

I use datatables with server_processing with numericComma with ColumnFilter with FixedHeader and scroller.

I would hope that the passage of a mouse line carries 300 milliseconds after a function. but I can not!
This will prevent this function is executed 10 times, if I pass very quickly with the mouse over 10 lines of the table...
In fact, I would like to start this function "search ()" only after 300 msec of inactivity of the mouse ...

Can you help me?

Below is the code in question (oTable + function onMouseOver)

Thank you in advance for your help.
Cordially.

$(document).ready(function() {
	url();
	var oTable = $('#example').dataTable( {
