To further explore the records within a particular topic cluster, use the Filter Topics feature. Simply single click on a topic box then click the Filter Topics button. If you are interested in multiple topic clusters, hold down the Ctrl (or Apple) key while clicking on the clusters then click Filter Topics.
The Topic Explorer visualization will recategorize the filtered records in a more appropriate Display Level, i.e. these records will now be shown with more specific topic boxes, and the results on the right side of the screen will also be updated.
You can also filter by topic using the Accessible Table. Click on Table, located above the visualization, and use the empty boxes adjacent to the Topics to select/check the topics you would like to include in your results. Click on Filter Topics once you are done with you selections. Remember that the Display levels indicate how granular the topics are that you are viewing.
Below the search bar, the Breadcrumbs adjacent to the “Active Filters” text denote which Display Level filters are on. Additionally, if you have applied other filters using the Refine Filters panel, these will also be shown in the breadcrumbs.
