Unable to click search

I am opening nseindia.Com URL in IE using vbscript. Entered stock name using VB script but unable to click search. Couldn't find search button so no object to click.

Manually I can enter stock name (eg ACC) and press enter button. It shows stock quote/details.

I need to do this using vbscript. Please guide or give code. Note- I don't want to use wshell or wscript object

Thanks in advance
