pass array or slice into go-elasticsearch search query - go

Question

I need to pass array or slice in my go-elasticsearch query for search.
for example:
filters := make([]json.RawMessage, 0)
channelids := []string{"2", "3", "4"}
termFilter, _ := json.Marshal(map[string]interface{}{"term": map[string]interface{}{"channelids": channelids}})
filters = append(filters, termFilter)
termFilter1, _ := json.Marshal(map[string]interface{}{"term": map[string]interface{}{"user": "kimchy"}})
filters = append(filters, termFilter1)
query, _ := json.Marshal(map[string]interface{}{
"query": map[string]interface{}{
"bool": map[string]interface{}{
"must": filters,
},
},
})
querybody1: {"query":{"bool":{"must":[{"term":{"channelids":["2","3","4"]}},{"term":{"user":"kimchy"}}]}}}
when I pass this query it through error:
{
"error" : {
"root_cause" : [
{
"type" : "x_content_parse_exception",
"reason" : "[1:49] [bool] failed to parse field [must]"
}
],
"type" : "x_content_parse_exception",
"reason" : "[1:49] [bool] failed to parse field [must]",
"caused_by" : {
"type" : "illegal_state_exception",
"reason" : "Can't get text on a START_ARRAY at 1:49"
}
},
"status" : 400
}
According to my findings it is due to {"channelids":["2","3","4"]}} in querybody1.
So,How can I manage it? or pass array in search query.
