Apache Solr Reference Guide Covering Apache Solr 6.0

The replace-field-type command replaces a field type in your schema. Note that you must supply the full
definition for a field type - this command will not partially modify a field type's definition. If the field type does not
exist in the schema an error is thrown.
All of the field type properties available when editing schema.xml by hand are available for use in a POST
request. The structure of the command is a json mapping of the standard field type definition, including the
name, class, index and query analyzer definitions, etc. Details of all of the available options are described in the
section Solr Field Types.
For example, to replace the definition of a field type named "myNewTxtField", you can make a POST request as
follows:
curl -X POST -H 'Content-type:application/json' --data-binary '{
"replace-field-type":{
"name":"myNewTxtField",
"class":"solr.TextField",
"positionIncrementGap":"100",
"analyzer":{
"tokenizer":{
"class":"solr.StandardTokenizerFactory" }}}
}' http://localhost:8983/solr/gettingstarted/schema
Add a New Copy Field Rule
The add-copy-field command adds a new copy field rule to your schema.
The attributes supported by the command are the same as when creating copy field rules by manually editing
the schema.xml, as below:
Name Required Description
source Yes The source field.
dest Yes A field or an array of fields to which the source field will be copied.
maxChars No The upper limit for the number of characters to be copied. The section Copying Fields
has more details.
For example, to define a rule to copy the field "shelf" to the "location" and "catchall" fields, you would POST the
following request:
curl -X POST -H 'Content-type:application/json' --data-binary '{
"add-copy-field":{
"source":"shelf",
"dest":[ "location", "catchall" ]}
}' http://localhost:8983/solr/gettingstarted/schema
Delete a Copy Field Rule
The delete-copy-field command deletes a copy field rule from your schema. If the copy field rule does not
exist in the schema an error is thrown.
The source and dest attributes are required by this command.
For example, to delete a rule to copy the field "shelf" to the "location" field, you would POST the following
request:
