How to identify whether user clicks on theSearch button or not in Expression based Record?

Hi,

We have expression based Record configures. As per the customer requirement we are not going to show any records list while loading(first time). we have to get the records/display the records only after clicking on the  Search button even though searchText is empty.

is there any way to identify or capture the default Search button click event means how to identify whether the user clicks on Search(default) button or not?

Thanks in advance.
