Description

As shown in the Schema API documentation
https://cwiki.apache.org/confluence/display/solr/Schema+API#SchemaAPI-AddaNewCopyFieldRule

when adding a new copy field rule, the maxChars argument can be also specified.

When trying to execute the request :

curl -X POST -H 'Content-type:application/json' --data-binary '{
  "add-copy-field":{
     "source":"name",
     "dest":[ "secondname"],
     "maxChars" : "3000"}
}' http://localhost:8983/solr/films/schema

(after creating a core

bin/solr create -c films

, and creating two text fields

curl http://localhost:8983/solr/films/schema -X POST -H 'Content-type:application/json' --data-binary '{
    "add-field" : {
        "name":"name",
        "type":"text_general",
        "stored":true
    },
   "add-field" : {
        "name":"secondname",
        "type":"text_general",
        "stored":true
    }
}'

the error message shown is

  "responseHeader":{
    "status":0,
    "QTime":1},
  "errors":[{
      "add-copy-field":{
        "source":"name",
        "dest":["secondname"],
        "maxChars":"3000"},
      "errorMessages":["Only the 'source' and 'dest' params are allowed with the 'add-copy-field' operation"]}]}

which occurs due to the handling in SchemaManager.java file

        if ( ! op.getValuesExcluding(SOURCE, DESTINATION).isEmpty()) {
          op.addError("Only the '" + SOURCE + "' and '" + DESTINATION
              + "' params are allowed with the 'add-copy-field' operation");
          return false;
        }
