Extra hops
From the widget "extra options" (gear icon), it is possible to set the document viewer to grab "2-hop" and "3-hop" queries. This means that after performing the additional query:
- (2-hops) a secondary query is performed to retrieve documents not matching the original query but containing one or more entities from the original query
- (3-hops) a third query not matching either the original query, or the "2-hop" query, but containing one or more entities from the "2-hop" query
This capability can slow the system down a fair bit, so should be used with caution.
Workspaces
The latest (Sep 2014+) version of the doc viewer has 2 tabs in the left pane:
The left tab, provides the workspace view:
The options ("sub-tabs") underneath that tab are:
- Buckets: lets users create lists of hand curated documents
- Queues: lets users specify queries that will periodically fill the list. New documents can also optionally generate alerts.

To remove a filter, click the button located just below the query bar, this will revert the workspace back to the original query results.
