  description: 'A best-effort OpenAPI 3.1 description of selected endpoints from the Apache

    Solr HTTP API, including the Collections (Cluster/Node Management), Schema,

    and v2 cluster APIs. Solr''s full APIs are exposed as v1 (action-style query

    parameters under `/solr/admin/*`) and v2 (resource-style paths under

    `/api/*`). Authentication is optional but BasicAuth is supported when the

    Solr `BasicAuthPlugin` is enabled.
