Elasticsearch queries not returning all results - elasticsearch

Question

I'm trying to learn Elasticsearch and I have an index with 8 documents. When I run the request (GET):
{
"query": {
"match_all" : {}
}
}
The response is:
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 8,
"relation": "eq"
},
"max_score": 1.0,
"hits": [
{
"_index": "el1",
"_type": "_doc",
"_id": "X5jGjXgB0p8Gz5z3KdFE",
"_score": 1.0,
"_source": {
"itemId": "01",
"curriculumId": "curriculum01",
"disciplineId": "discipline01"
}
},
{
"_index": "el1",
"_type": "_doc",
"_id": "YJjGjXgB0p8Gz5z3eNH4",
"_score": 1.0,
"_source": {
"doc": {
"itemId": "02",
"curriculumId": "curriculum01",
"disciplineId": "discipline02"
}
}
},
{
"_index": "el1",
"_type": "_doc",
"_id": "YZjGjXgB0p8Gz5z3jdHN",
"_score": 1.0,
"_source": {
"doc": {
"itemId": "03",
"curriculumId": "curriculum02",
"disciplineId": "discipline01"
}
}
},
{
"_index": "el1",
"_type": "_doc",
"_id": "YpjGjXgB0p8Gz5z3tdHl",
"_score": 1.0,
"_source": {
"doc": {
"itemId": "04",
"curriculumId": "curriculum02",
"disciplineId": "discipline02"
}
}
},
{
"_index": "el1",
"_type": "_doc",
"_id": "Y5jGjXgB0p8Gz5z3w9Gx",
"_score": 1.0,
"_source": {
"doc": {
"itemId": "01",
"curriculumId": "curriculum01",
"disciplineId": "discipline01"
}
}
},
{
"_index": "el1",
"_type": "_doc",
"_id": "ZJjGjXgB0p8Gz5z30NF5",
"_score": 1.0,
"_source": {
"doc": {
"itemId": "02",
"curriculumId": "curriculum01",
"disciplineId": "discipline02"
}
}
},
{
"_index": "el1",
"_type": "_doc",
"_id": "ZZjGjXgB0p8Gz5z33NHI",
"_score": 1.0,
"_source": {
"doc": {
"itemId": "03",
"curriculumId": "curriculum02",
"disciplineId": "discipline01"
}
}
},
{
"_index": "el1",
"_type": "_doc",
"_id": "ZpjGjXgB0p8Gz5z36dE1",
"_score": 1.0,
"_source": {
"doc": {
"itemId": "03",
"curriculumId": "curriculum02",
"disciplineId": "discipline02"
}
}
}
]
}
}
It has all my documents. But if I run this other request (GET):
{
"query": {
"match" : {"disciplineId": "discipline01"}
}
}
It returns just the first document, and if I change it do "discipline02" it returns nothing.
The same happens to the other fields. What I'm doing wrong? I already tried using size:"10" but it doesn't seems to work (I think the default size is already 10).
I'm running this docker image and sending the requests with Insomnia.

Answer 1

Only the first document is in this format
{
"itemId": "01",
"curriculumId": "curriculum01",
"disciplineId": "discipline01"
}
Rest all document are in this format
{
"doc": {
"itemId": "02",
"curriculumId": "curriculum01",
"disciplineId": "discipline02"
}
}
Modify your query as
{
"query": {
"match": {
"doc.disciplineId": "discipline02" // note this
}
}
}
