ElasticSearch - Sort does not work - sorting

Question

I'm trying make a search and sort the results. However, I'm getting a error dont know why.
EDIT - I'll provide my full mappings.
"myindex": {
"mappings": {
"mytype": {
"dynamic_templates": [
{
// Dynamic templates here!
}
],
"properties": {
"fieldid": {
"type": "keyword",
"store": true
},
"fields": {
"properties": {
"myfield": {
"type": "text",
"fields": {
"sort": {
"type": "keyword",
"ignore_above": 256
}
},
"analyzer": "myanalyzer"
}
}
},
"isDirty": {
"type": "boolean"
}
}
}
}
}
}
When I performed a search with sorting, like this:
POST /index/_search
{
"sort": [
{ "myfield.sort" : {"order" : "asc"}}
]
}
I get the following error:
{
"error": {
"root_cause": [
{
"type": "query_shard_exception",
"reason": "No mapping found for [myfield.sort] in order to sort on",
"index_uuid": "VxyKnppiRJCrrnXfaGAEfA",
"index": "index"
}
]
"status": 400
}
I'm following the documentation on elasticsearch.

Hmm it might be your mapping isn't set properly. I followed along using the following:
PUT /your-index/
{
"settings": {
"number_of_replicas": "1",
"number_of_shards": "3",
"analysis": {
"customanalyzer": {
"ID": {
"type": "custom",
"tokenizer": "keyword",
"filter": ["lowercase"]
}
}
}
},
"mappings": {
"thingy": {
"properties": {
"myfield": {
"type": "text",
"analyzer": "ID",
"fields": {
"sort": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
}
}
To double check if the index actually has myfield.sort field look at
GET /your-index/thingy/_mapping
Then, upload some document (no need to specify the sub-field(s), elasticsearch will do it for you)
POST /your-index/thingy/
{
"myfield": "some-value"
}
Now I can search with the following:
POST /your-index/thingy/_search
{
"sort": [
{ "myfield.sort": { "order": "asc" } }
]
}
So be sure to check:
Naming/typo's (you never know)
Your mapping (does it have the "myfield.sort" field)
Are you searching in the correct index?
Hopefully this helps
