Hello, Is there a way to use the percolator in the new version of Elasticsearch (8.8.2) with the Java API? my index mapping ```auto { "my_index_1": { "mappings": { "dynamic": "strict", "properties": { "email": { "type": "keyword" }, "id": { "type": "integer" }, "name": { "type": "text" }, "query": { "type": "percolator" } } } } } ``` I cannot save a percolator field to my index with the Java API . Before version 8.0, I was using PerculateQueryBuilder. Is this now deprecated? thanks. ---

No. See [Percolator field type | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/percolator.html). ---

Thanks for replying @dadoonet > [@dadoonet](#): > > No. See [Percolator field type | Elasticsearch Guide [8.10] | Elastic ](https://www.elastic.co/guide/en/elasticsearch/reference/current/percolator.html). I can't find an equivalent in the Java API **MyObjectModel.java** ```auto public class MyObjectModel { private String id; private String name; private String email; private PercolateQuery query; // ? } ``` **SearchService.java** ```auto public void save(RequestModel requestModel) throws IOException { PercolateQuery percolateQuery = getPercolateQuery(requestModel); MyObjectModel myObjectModel = MyObjectModel.builder() .id(requestModel.getId().toString()) .email(requestModel.getEmail()) .name(requestModel.getName()) .query(percolateQuery) .build(); elasticRepository.saveToElasticsearch(myObjectModel.getId(), myObjectModel); } private PercolateQuery getPercolateQuery(RequestModel requestModel) { BoolQuery.Builder boolQueryBuilder = new BoolQuery.Builder(); if (requestModel.getEmail() != null) { boolQueryBuilder.filter(q1 -> q1.term(q2 -> q2.field("email").value(requestModel.getName()))); } Query query = boolQueryBuilder.build()._toQuery(); JsonData jsonData = JsonData.fromJson(new Gson().toJson(query)); return PercolateQuery.of(x->x.field("query").document(jsonData)); } ``` **ElasticRepository.java** ```auto public void saveToElasticsearch(String id, MyObjectModel myObjectModel) throws IOException { elasticsearchClient.index(i -> i.index(myIndexAlias).id(id).document(myObjectModel)); } ``` **Error

PercolateQueryBuilder is deprecated. Can use /\_bulk update to save json-Query as an asset with fields to index. And for percolate action One option is to use custom builder with - Java Map as lowlevel to generate percolate and use any JsonobjectMapper and use /search API ```plaintext { "query": { "percolate": { "field": "query", "document": { "id": "", "type": "" } } } } ``` ---
