After an upgrade made to 6.2 our scrolling does no longer work. We are currently using a java client for it that follows the docs for first and subsequent requests ([https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-scroll.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-scroll.html)). To avoid any noise with the java client the requests are also done in the Kibana console and results confirm the issue. More details to follow
The example on the rest API is as follow:
First search request:
```
POST /cipher/_search?scroll=1m
{"size":500,"query":{"bool":{"must":[{"match_all":{"boost":1.0}}],"adjust_pure_negative":true,"boost":1.0}},"post_filter":{"has_child":{"query":{"bool":{"must":[{"bool":{"should":[{"term":{"processId":{"value":"511e1-v053-947a5-966d30281c4c16ad10c084533edd4a_511e1-v053-947a5-966d30281c4c16ad10c084533edd4a","boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}},{"bool":{"should":[{"match":{"clusterId":{"query":0,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":1,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":2,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":3,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":4,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":5,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":6,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":7,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":8,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":9,"operator":"OR","prefix_length":0,"max_expansions":50,"fuzzy_transpositions":true,"lenient":false,"zero_terms_query":"NONE","auto_generate_synonyms_phrase_query":true,"boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}}],"adjust_pure_negative":true,"boost":1.0}},"type":"process","score_mode":"none","min_children":0,"max_children":2147483647,"ignore_unmapped":false,"boost":1.0,"inner_hits":{"ignore_unmapped":false,"from":0,"size":3,"version":false,"explain":false,"track_scores":false}}},"explain":false,"_source":{"includes":["grantedTerritories","priorityDate","patentNumbers","accession","title","status"],"excludes":[]}}
```
It returns 500 results:
```
{
"_scroll_id": "DnF1ZXJ5VGhlbkZldGNoBQAAAAAAADX9Fkc1SEtPaE96UTllUEljcUJoZ3cyVmcAAAAAAAA1_hZHNUhLT2hPelE5ZVBJY3FCaGd3MlZnAAAAAAAANf8WRzVIS09oT3pROWVQSWNxQmhndzJWZwAAAAAAADYAFkc1SEtPaE96UTllUEljcUJoZ3cyVmcAAAAAAAA2ARZHNUhLT2hPelE5ZVBJY3FCaGd3MlZn",
"took": 396,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 1075,
"max_score": 1,
"hits": [ {
"_index": "cipher",
"_type": "_doc",
"_id": "5254018",
"_score": 1,
"_source": {
"grantedTerritories": [
"DE",
"CH",
"GB",
"FR"
],
...]
}
}
```
Then it follows the search scroll:
```
POST /_search/scroll
{
"scroll" : "1m",
"scroll_id" : "DnF1ZXJ5VGhlbkZldGNoBQAAAAAAADX9Fkc1SEtPaE96UTllUEljcUJoZ3cyVmcAAAAAAAA1_hZHNUhLT2hPelE5ZVBJY3FCaGd3MlZnAAAAAAAANf8WRzVIS09oT3pROWVQSWNxQmhndzJWZwAAAAAAADYAFkc1SEtPaE96UTllUEljcUJoZ3cyVmcAAAAAAAA2ARZHNUhLT2hPelE5ZVBJY3FCaGd3MlZn"
}
```
But it returns the following (please note the empty array of hits):
```
{
"_scroll_id": "DnF1ZXJ5VGhlbkZldGNoBQAAAAAAADX9Fkc1SEtPaE96UTllUEljcUJoZ3cyVmcAAAAAAAA1_hZHNUhLT2hPelE5ZVBJY3FCaGd3MlZnAAAAAAAANf8WRzVIS09oT3pROWVQSWNxQmhndzJWZwAAAAAAADYAFkc1SEtPaE96UTllUEljcUJoZ3cyVmcAAAAAAAA2ARZHNUhLT2hPelE5ZVBJY3FCaGd3MlZn",
"took": 1,
"timed_out": false,
"terminated_early": true,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 1110,
"max_score": 1,
"hits": []
}
}
```
What am I missing to get the next batch?

This problem seems to be related with the "post\_filter" object on the initial request, that in turn comes from doing a parent\_child request, namely:
"post\_filter":{"has\_child":{"query":{"bool":{"must":[{"bool":{"should":[{"term":{"processId":{"value":"511e1-v053-947a5-966d30281c4c16ad10c084533edd4a\_511e1-v053-947a5-966d30281c4c16ad10c084533edd4a","boost":1.0}}}],"adjust\_pure\_negative":true,"boost":1.0}},{"bool":{"should":[{"match":{"clusterId":{"query":0,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":1,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":2,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":3,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":4,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":5,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":6,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":7,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":8,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}},{"match":{"clusterId":{"query":9,"operator":"OR","prefix\_length":0,"max\_expansions":50,"fuzzy\_transpositions":true,"lenient":false,"zero\_terms\_query":"NONE","auto\_generate\_synonyms\_phrase\_query":true,"boost":1.0}}}],"adjust\_pure\_negative":true,"boost":1.0}}],"adjust\_pure\_negative":true,"boost":1.0}},"type":"process","score\_mode":"none","min\_children":0,"max\_children":2147483647,"ignore\_unmapped":false,"boost":1.0,"inner\_hits":{"ignore\_unmapped":false,"from":0,"size":3,"version":false,"explain":false,"track\_scores":false}}}

It seems related with this issue: [No hit using scan/scroll with has\_parent filter](https://discuss.elastic.co/t/no-hit-using-scan-scroll-with-has-parent-filter/15143/4)
However I'm using 6.2 API, shouldn't that be fixed?
...
SearchRequest searchRequest = new SearchRequest(CIPHER\_INDEX)
.source((new SearchSourceBuilder()
.query(QueryBuilders.boolQuery().must(getMatchQuery(searchFor)))
.postFilter(JoinQueryBuilders.hasChildQuery(ElasticConstants.CHILD\_JOIN\_REL,
filterByProcessAndCluster(reportMetadata.target().process(), processes, allClusters),
ScoreMode.None)
.innerHit(new InnerHitBuilder()))
.explain(false)))
.types(CIPHER\_TYPE)
.searchType(SearchType.QUERY\_THEN\_FETCH);
...
elasticClient.search(searchRequest);
...
elasticClient.searchScroll(new SearchScrollRequest(result.getScrollId()))
...
