Filtering by document format

While the HDDS facility is active, the Search Results page lists the document formats of the objects in the search results, along with the number of returned objects in each format. The document format of an object is the format of its data content before that data was added to the namespace. Examples of document formats are PDF, JPEG, and XML.

The document formats on the Search Results page are listed in descending order of frequency. You can select only one document format to use as a filter in any given search.

When you select a document format, the Search Results page redisplays the search results, including only objects whose content is in the selected format. The name of the format appears in the Active result filters area.

Objects with an unrecognized format are listed as Unknown format. Objects whose content is larger than ten MB or whose compressed content expands to more than ten MB are also listed this way. Additionally, plain text objects that use EBCDIC encoding are listed this way.

For information on the document formats recognized by HDDS for search operations, see the applicable HDDS documentation.
