+Software Heritage - Search service
 ==================================
 
 The SWH search service, or swh-search, stores a partial copy of
 the |swh| archive.
 It is similar to swh-storage in what it contains,
 but provides different ways to query it: while swh-storage is mostly
 a key-value store that returns an object from a primary key,
 swh-search is focused on reverse indices, to allow finding objects that
 match some criteria; for example full-text search.
 
 It is currently based on Elasticsearch, allowing full-text search on both
 URLs (using a ``search_as_you_type`` index) and on intrinsic metadata of
 their head revision in CodeMeta_ format.
 
 It is kept in sync with :ref:`the main SWH storage <swh-storage>` via
 :ref:`the SWH journal <swh-journal>`.
