Faceting enables you to rapidly see distinctive values in a column, make changes to those values, and customize your display to only display results that match a given aspect.
To display facet:
1. Click the arrow button on the column header of the column you want to analyze.
2. From the drop-down menu, choose "Facet," then select "Text facet."
3. In the grid view's pane on the left, a facet window will show.
