Search results can be filtered in multiple ways. The main way to access filters is to click on the Filters button:
This opens a panel in you can select one or more filter criteria that should be applied to further filter the search results down to just what you are looking for:
Filters are available for entities, nouns, verbs, classes (file classifications) and file extensions. The numeric value appearing next to each filter item choice is the number of items in the current search results to which that filter item applies. For example, in the example above, the verb "show" appears in ten of the search results.
Filtering the search results will not only reduce the amount of items to zero in on what you are looking for, but the search summary text snippets for those search results will have highlighted values pointing out where those filtered terms were found (where applicable)
