Introduction

The Vuze Distributed Database, or DHT as it is also known, it used for many features in the client. It provides a relatively resilient way to store small amounts of information about things like torrents in a distributed manner - see The DHT Overview for more information. Here are some of its uses:

  • Decentralized tracking - for non-private torrents that you are downloading the seeds and peers in the swarm locate each other without the need for a centralized tracker by registering their presence in the DHT against the torrent.
  • Magnet downloads - when you use a magnet link to download a torrent this is mediated by the DHT.
  • Subscriptions - links between torrents and the subscriptions (e.g. RSS feeds) that provided them.
  • Ratings and comments - if you use the ratings plugin supplied with Vuze then your rating and comment details .
  • Friends - a means of sharing content and chatting - see Friends
  • NAT Traversal - Rendezvous nodes are maintained in the DHT to help you receive incoming UDP connections when firewalled

Discoveries

Swarm Discoveries adds to this by extending the existing subscriptions feature to allow the relationship between torrents to be recorded. Instead of storing the relationship between a torrent and a subscription in the DHT the Vuze client stores the relationship between one torrent and another. Statistical analysis is then automatically used by other Vuze clients to extract the significant relationships from the millions of torrent hash links to provide you with a list of things that may be of interest.

'Cloud Discoveries' might be a more accurate word for this, as it is the super-imposition of all the swarms from which this data is aggregated. However, everything is 'Cloud' something these days so 'Swarm' was chosen.

Once you are in the Swarm Discoveries view you can dive into deeper relationships by selecting an entry and right-clicking to obtain the 'Discover Related' menu option. This will open a subview that shows things explicitly related to your selection. When you do this the ranking of the results will be low (i.e. less correlated).

A similar menu option is available in the Library views to do the same for content in your Library:

The sidebar has a context menu that gives you a few options:

  • Lookup Subscriptions - this performs an exhaustive look-up for subscriptions related to content in the Swarm Discoveries view
  • Mark All Read - marks the current content in the view as read
  • Delete All Results - deletes all the entries in the current view and prevents them from being shown again
  • Reset to Initial State - deletes all the entries in the view and proceeds as if start of day

Search

Swarm Search integrates with the existing meta-search (we strongly encourage your to review the Meta Search FAQ) function within Vuze to automatically bring you results from the various data-sets created by 'Swarm Discoveries'. It is not an exhaustive or deterministic search and in general different results will be returned each time a search is attempted. In particular it takes a while to 'warm up' after Vuze is started.

Subscriptions

As with any other search source you can create a subscription from a Swarm Search. This will cause the search to be periodically re-run and any new results will appear in the subscription as new items. This is particularly useful as Swarm Search results are non-deterministic, meaning you will in general get different results every time you run the same query. To do this you need to perform the desired search and then click on the RSS icon at the top of the search and follow the instructions.

Configuration

The feature as a whole, or parts thereof can be enabled and disabled by the Swarm Discoveries plugin configuration - see Tools->Options->Plugins->Swarm Discoveries.

Vuze® Pre-Selected Tracker Sites

Currently in Beta

While using tracker sites is not necessary for Swarm Discovery to work, Swarm Discovery users may user trackers. Users may use a Vuze pre-selected list of tracker sites, which Vuze has provided as a convenience to Vuze users. Vuze does not have any relationship with the pre-selected tracker sites cannot attest to the legitimacy, safety or completeness of any content that may be identified through such sites. Vuze selected and selects these torrent sites because it has a good faith and reasonable belief that those sites track or host content, the overwhelming majority of which content does not infringe upon the rights, including copyright, of any third party. Vuze attempts to determine the legitimacy and legality of these sites -- regarding those sites mostly or exclusively involving non-infringing content -- based upon news reports, outcomes of lawsuits or governmental actions against those sites, as well as periodically examining the number of take-down requests received by Google for domains alleged to be associated with infringing content. (See, Google Transparency Report, and we encourage you to read Google's official blogs about its Transparency report.) Vuze recognizes that simply because Google might receive a lot of take-down requests associated with a domain that does not necessarily mean that there is a lot of infringing content available on or through such sites, because take-down requests are simply allegations of infringement, not proof that there was or is infringement, many take-down requests are false, abusive, do not take into account "fair use" under the United States Copyright Act and analogous laws of other territories or countries, and might even be based upon falsified court orders. Further, there are reports that many take-down request involve attempts to suppress political speech. However, if Vuze becomes aware of an exceptionally high number of take-down requests associated with a domain that has been in existence for a reasonable period of time Vuze will typically not include, or will remove, such site from its pre-selected list.

Vuze users assume, and Vuze disclaims, all risks including of using those pre-selected tracker sites. To the extent that some Vuze users have occasionally received or might occasionally receive notices from ISPs regarding the downloading of allegedly unlawful copies of content, Vuze believe these arise from the downloading of content outside the Vuze HD Network. It is each user's responsibility to ensure that they are only downloading lawful and non-infringing content -- wherever it may be found. One such source of lawful content is the Vuze HD Network. In any event, Vuze strongly urges each user to act responsibly when it comes to downloading and sharing content.

Privacy

When a content relationship is stored in the DHT it is done so anonymously. When another client looks up a relationship no information about the relationship originator is available. The search function works purely on content relationships, not on downloads themselves.

Important Rights & Use Note

Swarm Discoveries and its search results on Vuze are drawn from a statistical view of content associations created by other Vuze clients on the internet and are automatically generated by the Vuze client. For tracker sites not included in those pre-selected by Vuze, we additionally warn that some of those tracker sites might be accused of being more likely to track torrent files that might infringe upon the rights of others, including copyright, and might include more "adult" content, some of which might be alleged to infringe upon the rights of others. Given how Swarm Discovery works, third party torrent files that might automatically be considered "related" to the torrent files on your device which files are found by way of "all" tracker sites might be "related" only by virtue of the fact that if you and other users have "ABC.torrent," for example, and many or some of those other users have "XXX.torrent," Swarm Discoveries might consider the "XXX.torrent" to be "related." If you choose to enable "all" tracker sites, you might want to take additional care in selecting what Swarm Discovery content you wish to download, as well as then make available for uploading. The content available through Vuze® or Vuze+™ may or may not comply with copyright laws, including copyright laws, in your territory and country, and Vuze is not responsible for content you may download or share. Vuze stresses that it respects the rights of copyrights holders and expects that you do and will too. Any use of Vuze® or Vuze+™ that violates an intellectual property right or any right of a third party is not allowed. Please do not infringe upon copyright. Read more on the Legal FAQ. Plus, if you are a Vuze user don't forget that you agreed to its Terms.
