How to tell ElasticSearch to create nested fields


How to tell ElasticSearch to create nested fields

I hope this helps you . By default, the dynamic mapping feature of ElasticSearch will map users as an object instead of nested.
If you want to tune this behavior, you have to define explicitely a users attribute as nested either in :

wish help you to fix your issue I think you are not checking this correctly, because your mapping looks good, the document being indexed looks good.
How I would check it is like this:
code :
GET /hmgshopmonitor/items/_search
{
  "query": {
    "nested": {
      "path": "taxonomyHMG",
      "query": {
        "term": {
          "taxonomyHMG.0": {
            "value": "Pullover & Strick"
          }
        }
      }
    }
  }
}

This might help you If you don't have a certain query that should match the nested fields somehow, you can do it like this:
code :
GET /index/_search
{
  "size": 10,
  "_source": ["nested_fields.id", "nested_fields.name"]
}
{
  "query": {
    "nested": {
      "path": "nested_fields",
      "query": {"match_all": {}}, 
      "inner_hits": {}
    }
  }
}

hope this fix your issue You can read this one https://www.elastic.co/guide/en/elasticsearch/guide/current/combining-filters.html It should help you.
SQL query:
code :
SELECT document
FROM   products
WHERE  productID = "KDKE-B-9947-#kL5"
OR (productID = "JODL-X-1937-#pV7" AND price = 30 )
{
  "query" : {
  "constant_score" : {
     "filter" : {
        "bool" : {
          "should" : [
            { "term" : {"productID" : "KDKE-B-9947-#kL5"}}, 
            { "bool" : { 
              "must" : [
                { "term" : {"productID" : "JODL-X-1937-#pV7"}}, 
                { "term" : {"price" : 30}} 
              ]
            }
           }
          ]
       }
     }
   }
 }

seems to work fine I have an index with the following structure. , After discussing, I think I understand your problem better:

wish of those help Nested objects are treated as separate docs, hence nested is needed in the query.
code :
GET my_app_name/my_model/_search
{
  "query": {
    "nested": {
      "path": "categories",
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "categories.name": "SomeCategoryName"
              }
            }
          ]
        }
      }
    }
  }
}
