Best way to index base64 encoded string into ElasticSearch
You might want to use the mapper-attachments plugin and declare your field with the Attachment field type
@Document(indexName = "user_record")public class UserRecord { @FieldType(type = FieldType.Attachment, store = false) private String base64UserUploadFile;...That way the Base64 content will be indexed and searchable. I suggest not to store the content (hence store=false) if you don't want to inflate your index unnecessarily.
