If your data contains subsets (e.g., star ratings, demographic information or product categories), click Select Subset > All Documents in the far-left pane of an open Analytics project to display a drop-down menu of your data's subsets.
Select your subset and a new Concept Cloud will instantly re-configure itself to display only the concepts within your selected subset. The number of documents contained in any particular subset displays in parentheses. The system will adjust a selected concept's number of exact vs conceptual matches according to the subset.
Subsets are easily created in the source data spreadsheet prior to being uploaded.
