How to fire Button Click Event when enter key is pressed Inside Textbox

Content

We have a form layout with 8-9 fields as search criteria and a button to fire search and populate a table beneath that. The requirement is if a person enters values in few field and press enter key instead of doing a mouse click on the search button the same event should get triggered that happens on the button click. 

Your inputs are greatly appreciated. Thanks in advance.
