* Collections API

You can use the [[https://lucene.apache.org/solr/guide/8_3/collections-api.html][collections API]] only when you run Solr in
Solr Cloud mode.

Otherwise you get the following error message:

{{{
Solr instance is not running in SolrCloud mode
}}}

* Field types

The field types coming with Solr are documented here: [[https://lucene.apache.org/solr/guide/8_3/field-types-included-with-solr.html#field-types-included-with-solr]]

However the field types needed for the API are a single word, e.g.

   boolean :: BoolField
   pdate :: DatePointField

You can find the API field name for each field in your Solr installation at =server/solr/configsets/_default/conf/managed-schema=.
