What is the best way to track the values being searched

Hi ,
I am currently using Datasearch component to search . I would like to track the values being used for the search . My using the debounce value as 1000 . I want to get the value being searched . i.e the value that is being exactly searched with elastic search (sent via ajax to the elastic server).

At this moment , am using onValuechange - but this method is giving data on each key stroke . (example : g , go , goo, goog , googl, google ). Am interested only with the "google" value as this is the value being sent to elastic search .

Note : I am not using auto suggestion and hence onValueSelected wont work .

Let me know the best way to handle this scenario .
