Terms query(ElasticSearch) not working for some field values - elasticsearch

Question

This is my Mapping where i have already declared my required field as keywordbut yet my terms query is not working for category_name and storeName but it is working fine for price.
"mappings": {
"properties" : {
"firebaseId":{
"type":"text"
},
"name" : {
"type" : "text",
"analyzer" : "synonym"
},
"name_auto" : {
"type": "text",
"fields": {
"edgengram": {
"type": "text",
"analyzer": "edge_ngram_analyzer",
"search_analyzer": "edge_ngram_search_analyzer"
},
"completion": {
"type": "completion"
}
}
},
"category_name" : {
"type": "text",
"fields": {
"keyword": {
"type": "keyword"
}
}
},
"storeName" : {
"type": "text",
"fields": {
"keyword": {
"type": "keyword"
}
}
},
"sku" : {
"type" : "text"
},
"price" : {
"type": "text",
"fields": {
"keyword": {
"type": "keyword"
}
}
},
"magento_id" : {
"type" : "text"
},
"seller_id" : {
"type" : "text"
},
"square_item_id" : {
"type" : "text"
},
"square_variation_id" : {
"type" : "text"
},
"typeId" : {
"type" : "text"
}
}
}
}
}
This is my query below :
{
"size": 0,
"aggs": {
"Category Filter": {
"terms": {
"field": "category_name",
"size": 10
}
},
"Store Filter": {
"terms": {
"field": "storeName",
"size": 10
}
},
"Price Filter": {
"range": {
"field": "price",
"ranges": [
{
"from": 0,
"to": 50
},
{
"from": 50,
"to": 100
},
{
"from": 100,
"to": 200
}
]
}
}
}
}
which returns as follows :
"reason": {
"type": "illegal_argument_exception",
"reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [category_name] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead."

Answer 1

You need to use the .keyword sub-field, like this:
{
"size": 0,
"aggs": {
"Category Filter": {
"terms": {
"field": "category_name.keyword", <-- change this
"size": 10
}
},
"Store Filter": {
"terms": {
"field": "storeName.keyword", <-- change this
"size": 10
}
},
"Price Filter": {
"range": {
"field": "price",
"ranges": [
{
"from": 0,
"to": 50
},
{
"from": 50,
"to": 100
},
{
"from": 100,
"to": 200
}
]
}
}
}
}
