Indexing Service (originally called Index Server) was a Windows service that maintained an index of most of the files on a computer to improve searching performance on PCs and corporate computer networks. It updated indexes without user intervention. In Windows Vista it was replaced by the newer Windows Search Indexer. The IFilter plugins to extend the indexing capabilities to more file formats and protocols are compatible between the legacy Indexing Service how and the newer Windows Search Indexer.
