Is there a tool in google chrome to search by request.data value on all http requests?

Question

JavaScript

Good afternoon,

The site is apparently on ASP.NET

There is a task to find an http request among a huge number.

The algorithm was as follows:
On the site professional.swarovski.com/ I enter ' 4120 ' into the search form
I get all the matches for this query visually. The following Url
is generated :

http://professional.swarovski.com/Portal.Node/portal?gentics.pa=triggerEvent&gentics.pb=&p.event=search

no mention of 4120 . So most likely everything here is Ajax or Rest .
But for some reason in chrome->firebug->network->xhr in NAME only .js files are displayed.

How can I dig up the correct request to find the url of the headers and data request ?
