How to filter entries in nested List by ID in nested List in elasticsearch with java?-CodePudding

Basically I do have a Set of a Records which has a Set of NestedRecords included:

Set<Record> records;

These are the classes:

public class Record {
  String id;
  Set<NestedRecord> nestedRecords;
}

public class NestedRecord {
  String nestedId;
  int count;
}

What I want to achieve is filter the out the entries in the nestedRecords list by a Set of nested ids. So I only want the nestedRecords in the List in Records which include the id's in my set nested Id's

Let's say this is my Set:

Set<String> nestedIds = new HashSet<String>() {{
add("a");
add("b");
}};

So this is how I do it, but it always filters out everything.

TermsQueryBuilder recordExists = QueryBuilders.termsQuery("NESTED_RECORDS.NESTED_ID",Lists.newArrayList(nestedIds).toString());

NestedQueryBuilder nestedRecords = QueryBuilders.nestedQuery("NESTED_RECORDS", recordExists, ScoreMode.Total);

BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();
boolQuery.must(nestedRecords);
query.filter(boolQuery);

CodePudding user response：

I think you are missing the path parameter in your nestedQuery call.

NestedQueryBuilder nestedRecords = QueryBuilders.nestedQuery("NESTED_RECORD", recordExists, ScoreMode.Total);

should be

NestedQueryBuilder nestedRecords = QueryBuilders.nestedQuery("nestedRecords", recordExists, ScoreMode.Total);

CodePudding user response：

I'm usually use Kotlin, so I don't know how java does it, but I think your toString() is wrong there

TermsQueryBuilder recordExists = nestedId.termsQuery("nestedRecords.nestedId",Lists.newArrayList(nestedIds).toString());

can be

TermsQueryBuilder recordExists = QueryBuilders.termsQuery("nestedRecords.nestedId", Lists.newArrayList(nestedIds));

and

NestedQueryBuilder nestedRecords = QueryBuilders.nestedQuery("NESTED_RECORD", recordExists, ScoreMode.Total);

NestedQueryBuilder nestedRecords = QueryBuilders.nestedQuery("nestedRecords", recordExists, ScoreMode.Total);
