Elasticsearch

Elasticsearch is a search and analytics engine that many sites use for site search, catalogues and document stores. This tag collects guides about building RSS and Atom feeds from Elasticsearch indexes. Articles explain how to filter published documents, sort by the real publication date and return only the fields that a feed needs. They also cover escaping text for XML, writing dates in the RFC 822 form, using document identifiers as stable guids and the refresh delay that makes new documents searchable. Security advice includes read-only API keys and keeping the cluster private. The tips help developers share every new item on social networks automatically.
