javascript - Elasticsearch: Matching documents with an array in it -

i'm new elasticsearch , documentation confuses me please bear me little bit here.

i have index called zproducts , under type called item mapped looks this:

{    "item_name" : "product a",    "category_ids" : [ "id1", "id2" ] }, {    "item_name" : "product b",    "category_ids" : [ "id1" ] }, {    "item_name" : "product c",    "category_ids" : [ "id2" ] } 

i want able query items match @ least 1 of of categories. ie. querying id2 return products , c.

it seem have exact same problem this guy had.

but solution suggested there doesn't work me.

this current query:

/zproducts/items/_search

{     "query": {         "bool": {             "must": [                 {                     "term": {                         "category_ids": "id2"                     }                 }             ]         }     } } 

subsequent test query:

{     "query": {         "filtered": {             "filter": {                 "term": {                     "category_ids": "id2"                 }             }         }     } } 

both queries return items on store , not ones i'm trying query for.

there original query which, reason, used work stopped working altogether.

{     "query": {         "bool": {             "must": [                 {                     "match": {                         "category_ids": {                             "query": "id2",                             "operator": "or"                         }                     }                 }             ]         }     } } 

so doing wrong here? can please shed light?

this query:

{     "query": {         "filtered": {             "filter": {                 "term": {                     "category_ids": "id2"                 }             }         }     } } 

is correct. make sure making request post /zproducts/items/_search, rather get /zproducts/items/_search - getting documents in index query hint query body being ignored, hint you're using get; many clients not send request body request, es interprets blank query.
