Briefly, this error occurs when the “_all” field is used in Elasticsearch versions 6.0 and above, where it has been deprecated. The “_all” field was used to search across all fields in a document. To resolve this issue, you can use the “copy_to” feature to copy the fields you want to a single combined field and search on that. Alternatively, you can use a custom “all” field that’s a concatenation of the fields you want to search. Lastly, you can use the “_source” field to search across all fields.

 if (mappingsByIndex.isEmpty() && types.length != 0) {
 builder.close();
 throw new TypeMissingException("_all"; String.join(";"; types));
 }  builder.startObject();
 {
 if (missingTypes.isEmpty() == false) {
