Hi all! I have an index with parent-child capability and the has\_child query below with a filter-range applied on children (child\_field\_1). My issues here are 2. 1. I cannot put multiple filters to children (only one), My query: ``` GET npk/_search { "query": { "has_child": { "type": "body", "min_children": 1, "query": { "range": { "child_field_1": { "gte": 5, "lte": 10 }, "child_field_2": { "gte": 8, "lte": 12 } } }, "inner_hits": {} } } } ``` Response: ``` "type": "parsing_exception", "reason": "[range] query doesn't support multiple fields, found [child_field_1] and [child_field_2]", ``` 1. I cannot put a filter for parent. My query: ``` GET npk/_search { "query": { "range": { "parent_field_1": { "gte": 1, "lte": 10 }}, "has_child": { "type": "body", "min_children": 1, "query": { "range": { "child_field_1": { "gte": 5, "lte": 10 } } }, "inner_hits": {} } } } ``` Response: ``` "type": "parsing_exception", "reason": "[range] malformed query, expected [END_OBJECT] but found [FIELD_NAME]", ``` ---

Here again with an ansewer to my question. I managed to insert multiple filters with multiple has\_child buckets, but it doesn't work 100%. I mean, it gives me results but not in the right range for field: `"gpsSats": {"gte": 17,"lte": 17}` . It brings me results also out of this range despite i have included in my query the " **must**" clause which stands for **AND**. What is wrong here? Any help please? My query: ```auto GET npk/_search { "_source": ["CameraNo"], "query": { "bool": { "must": [ { "range": { "CameraNo": { "gte": 1, "lte": 4 } } }, { "has_child": { "type": "body", "query": { "range": { "gpsSats": { "gte": 17, "lte": 17 } } } } }, { "has_child": { "type": "body", "query": { "range": { "ndvi_1": { "gte": 0.4, "lte": 0.5 } } } } }, { "has_child": { "type": "body", "query": { "range": { "ndvi_0": { "gte": 0.494, "lte": 0.495 } } }, "inner_hits": {"_source": ["ndvi_0","ndvi_1","gpsSats"]} } } ] } } } ``` ---

can you provide a **full, but minimal reproduction** including index creation & mapping, document indexing, the query you are executing, plus documents that get returned compared to what you expect? You can use the `inner_hits` query to check which children have matched, in case that helps debugging. Thank you! ---

index creation: ``` PUT /npk { "settings" : { "index" : { "number_of_shards" : 3, "number_of_replicas" : 2 } }, "dynamic": true, "mappings": { "doc": { "properties": { "my_join_field" : { "type" : "join", "relations": { "header": "body" }} }}} ``` A sample of documents indexed. Practically, it's a log file in which as 'parent' i used the header of this file (the vertical list with the fields with '#' in front of). And below this, it's the body of the file, which acts as 'children'. ![image](https://us1.discourse-cdn.com/elastic/original/3X/f/b/fb7f2dcaaab3c8d42d2454b35dbb15f73075060f.png) Below, is a part of an answer i get and as you see, the field "gpsSats" has brought to me values '17' which are correct, but also values '20' which are out of range i specified. ``` { "took": 35, "timed_out": false, "_shards": { "total": 3, "successful": 3, "skipped": 0, "failed": 0 }, "hits": { "total": 6, "max_score": 4, "hits": [ { "_index": "npk", "_type": "doc", "_id": "1", "_score": 4, "_source": { "CameraNo": 3 }, "inner_hits": { "body": { "hits": { "total": 53, "max_score": 1, "hits": [ { "_index": "npk", "_type": "doc", "_id": "12013", "_score": 1, "_routing": "1", "_source": { "ndvi_1": 0.563597, "ndvi_0": 0.494044, "gpsSats": 17 } }, { "_index": "npk", "_type": "doc", "_id": "12065", "_score": 1, "_routing": "1", "_source": { "ndvi_1": 0.555584, "ndvi_0": 0.494376, "gpsSats": 17 } }, { "_index": "npk", "_type": "doc", "_id": "12074", "_score": 1, "_routing": "1", "_source": { "ndvi_1": 0.562169, "ndvi_0": 0.494615, "gpsSats": 17 } } ] } } } }, { "_index": "npk", "_type": "doc", "_id": "51798", "_score": 4, "_source": { "CameraNo": 3 }, "inner_hits": { "body": { "hits": { "total": 53, "max_score": 1, "hits": [ { "_index": "npk", "_type": "doc", "_id": "52858", "_score": 1, "_routing": "1", "_source": { "ndvi_1": 0.511705, "ndvi_0": 0.494054, "gpsSats": 20 } }, { "_index": "npk", "_type": "doc", "_id": "52895", "_score": 1, "_routing": "1", "_source": { "ndvi_1": 0.522266, "ndvi_0": 0.494395, "gpsSats": 20 } }, { "_index": "npk", "_type": "doc", "_id": "52917", "_score": 1, "_routing": "1", "_source": { "ndvi_1": 0.523934, "ndvi_0": 0.494879, "gpsSats": 20 } } ] } } } } } ``` **Notes** : '_CameraNo_' is a parent field and '_ndvi\_0_', '_ndvi\_1_', '_gpsSats_' are children fields. ---
