- On your search results page, click the filter icon to open the Filters panel.
- Select the filters to apply. Click Show all to display all filters in a large category, or enter a search term to find a specific filter.
TAGS When you select multiple tags, you will see documents with any one of the tags. If you want to search for documents that contain all of the tags, use the search string tag(first tag) & tag(second tag).

The first level in the INGEST LOCATION filter category is the custodian. If you select the name, the list will be narrowed by documents found in all of the ingests with this custodian.
The second level is the name of the ingest session. If you select one, the list will be narrowed by documents found in that particular ingest.
The third level is the file paths from that ingest session. Expand the ingest session name and each individual folder to navigate through the file paths. Once you select a folder, the list will be narrowed by documents found in that folder and its subfolders.
Selecting a filter in one metadata field will affect the counts displayed in other metadata fields.
