The Query Builder can be customized to your customers' needs in many ways. One of them is offering reduced functionality to those customers who prefer to work with a subset of data sources available on the DataSift platform. If you want to see how that could work in practice, try creating a new filter using the instance of the Query Builder embedded below on this page. It only allows users to filter against 2channel or IMDb. If you would like to know more, read our configuration guide and check the reduced functionality example. You can download the code used to create this demo.
