I have created support ticket twice, but no reply. Not recommended if you are using K2 Joomla
The Live Search uses the search plugins, to show the result list. These search plugins from the 3rd party developers as your components. If these developers don't build a function to the search plugins - in this case the category exclusion - it is not a bug or mistake of the Live Search. We have many improved plugins, what contains many more features, and based on the original ones. If a customer need a feature, just write a support ticket, and we will help as always. This is how it has been worked many times.
We haven't found your support ticket. Please send your ticket number to info[at]offlajn.com, and we will help you immediately.
