OpenAPI Specification

openapi: 3.1.0
info:
  title: Apache Solr REST Collections API
  version: v2
  summary: HTTP/REST API for Apache Solr v2 covering collections, cores, schema, configuration, update and query handlers.
  description: 'Apache Solr exposes a REST API under /api (v2) on each Solr node. This specification

    covers collection lifecycle, core administration, per-collection schema/config/update

    operations, and the legacy Collections admin handler still supported under

    /solr/admin/collections.


    Authentication is pluggable (Basic, JWT, Certificate). Where security is enabled,

    Basic authentication is the most common configuration.
