Creating EnumType Solr using SolrJ

Question

I need to create a schema which will containt few enums. I\'m trying to do that using SolrJ. I\'ve found this link DefininganEnumFieldinschema but I couldn\'t find any examples

Answer 1

First you need to specify your enum field in schema, like in the documentation:

<fieldType name="myEnumField" class="solr.EnumField" enumsConfig="enumsConfig.xml" enumName="attribute"/>

in the enumsConfig.xml you will specify all your enum values, like:

<?xml version="1.0" ?>
<enumsConfig>
  <enum name="attribute">
    <value>sponsored</value>
    <value>generic</value>
  </enum>
</enumsConfig>

Alternatively, you could create this fieldType dynamically via Schema API as follows:

curl -X POST -H 'Content-type:application/json' --data-binary '{
  "add-field-type" : {
     "name":"myEnumField",
     "class":"solr.EnumField",
     "enumsConfig":"enumsConfig.xml",
     "enumName" : "attribute"}
}' http://localhost:8983/solr/demo/schema

You could do this as well in SolrJ fashion, by using org.apache.solr.client.solrj.request.schema.SchemaRequest.AddFieldType, you need to specify FieldTypeDefinition, method setAttributes(Map<String,Object> attributes) will be helpful
