Hi Hari,
I'm not sure if you read my previous post but the issue was not with if the search working or not, the issue was that the result that HG Insights produced did not have the necessary data. I want to find companies using Kentico CMS and HG Insights search page has this option under Vendor and Products.
I checked 20 or so webites manually with Builtwith chrome extension and gort only 1 hit.
Since I paid over 800 credits for my first search and additional 1300 credits for my second search (together with builtwith enrichment), the result was domain names (great) with vast majority not using Kentico (not so great)
In this case I believe I should get the credits back.
