Apache Solr Reference Guide Covering Apache Solr 6.0

only three fields in the initial schema: id , _version_, and _text_.
You can use the /schema/fields Schema API to confirm this: curl http://localhost:8983/solr/get
tingstarted/schema/fields will output:
{
"responseHeader":{
"status":0,
"QTime":1},
"fields":[{
"name":"_text_",
"type":"text_general",
"multiValued":true,
"indexed":true,
"stored":false},
{
"name":"_version_",
"type":"long",
"indexed":true,
"stored":true},
{
"name":"id",
"type":"string",
"multiValued":false,
"indexed":true,
"required":true,
"stored":true,
"uniqueKey":true}]}
Because the data_driven_schema_configs config set includes a copyField directive that causes
all content to be indexed in a predefined "catch-all" _text_ field, to enable single-field search that
includes all fields' content, the index will be larger than it would be without the copyField. When you
nail down your schema, consider removing the _text_ field and the corresponding copyField directiv
e if you don't need it.
Configuring Schemaless Mode
As described above, there are three configuration elements that need to be in place to use Solr in schemaless
mode. In the data_driven_schema_configs config set included with Solr these are already configured. If,
however, you would like to implement schemaless on your own, you should make the following changes.
Enable Managed Schema
As described in the section Schema Factory Definition in SolrConfig, Managed Schema support is enabled by
default, unless your configuration specifies that ClassicIndexSchemaFactory should be used.
You can configure the ManagedIndexSchemaFactory (and control the resource file used, or disable future
modifications) by adding an explicit like the one below, please see Schema Factory
Definition in SolrConfig for more details on the options available.
