index percolate queries using spring data jpa - spring-data-elasticsearch

Question

Here is my Dto for percolator query class.
#Data
#Document(indexName = "#{#es.indexName}")
#Builder(builderClassName = "RuleBuilder")
public class Rule {
#Id
private String id = UUID.randomUUID().toString();
private QueryBuilder query;
private RuleDataDto data;
public static class RuleBuilder {
private String id = UUID.randomUUID().toString();
}
}
Index Mapping
{
"mappings": {
"properties": {
"query": {
"type": "percolator"
},
"data": {
"properties": {
"subType": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"type": {
"type": "text",

}
}
based on criteria I am generating queries and trying to index those to percolator. but getting below exception
query malformed, no start_object after query name
what should be the query field Type? can someone help me on this

Answer 1

You are trying to store an Elasticsearch object (QueryBuilder) in Elasticsearch without specifying the mapping type.
You will need to annotate your query property as percolator type and might change the type of your property to a String:
#Document(indexName = "#{#es.indexName}")
public class Rule {
#Id
private String _id;
#Field(type = FieldType.Percolator)
private String query;
// ...
}
Or, if you want to have some other class for the query property you'll need a custom converter that will convert your object into a valid JSON query - see the documentation for the percolator mapping.
