What is a torrent indexer? A technical definition
A torrent indexer is a searchable catalog of torrent metadata or references. Indexing, peer discovery and transferring file data are distinct functions. A catalog listing does not establish permission to download or share a file.
Indexer, tracker and peers are different roles
- Indexer: helps users search metadata or references associated with torrents. An indexer may also offer other services; the term alone does not establish what a particular operator hosts.
- Tracker: helps a BitTorrent client discover peers participating in a torrent. Tracker-based discovery is not mandatory; distributed peer discovery also exists.
- Peers: clients that exchange pieces of file data. A swarm is the group of peers participating in a particular torrent, not a universal catalog of all available files.
BitTorrent does not require a central file server, but deployments can use centralized trackers, websites or initial distributors. A torrent can also be distributed directly by its publisher without an indexer.
What metadata tells you
Metadata can include filenames, sizes and technical identifiers. An info hash identifies torrent metadata under the relevant BitTorrent specification; it is not simply a checksum of a movie file. Names and descriptive tags can be inaccurate. A listing does not prove that peers are available, that the data is safe or that distribution is authorized.
Lawful use and limits
BitTorrent can distribute publisher-authorized software or other files. The protocol and the presence of a listing do not determine whether a particular use is permitted. Permission to receive a copy and permission to redistribute it can differ. Follow the applicable license, provider terms and local law.

MIRA Player is not an indexer
MIRA Player does not find, supply or index content sources or torrents for you. It is a media player for compatible sources you bring yourself. MIRA does not host content or download torrents on its hardware. A MIRA membership supplies no content rights.
