Below the Overview Map is a list of Filters, which are used to refine a search. The default filters are: Type, Subtype, Format, Geometry Type, Properties, Author, Spatial Reference, File Extension and Location, but they are configurable. The Show Inverse Option filters on the opposite value of any existing filter.

Within the Filters section, Field Statistics shows the total size, average size, and deviation for all files in the index.

Depending on the user's permission level, Admin Options may be available from the Filters section. The following actions can be taken on the current set of results:

• Remove from the index, with the option of also deleting the corresponding thumbnails, metadata, and layer files
• Add results to the discovery queue, which re-indexes the items immediately
• Show the underlying query
