Elastic search sublist query with and logic - elasticsearch

Question

I have post below json data:
[
{
"id": 1,
"shopname": "seven up",
"shopkeeper": "John",
"salesbooks": [
{
"bookid": 11,
"bookname": "Tom-story",
"soldout": false
},
{
"bookid": 12,
"bookname": "Iron-Man",
"soldout": true
}
]
}
]
and I make a simple elastic query as below:
{
"from": 0,
"query": {
"bool": {
"must": [
{
"wildcard": {
"salesbooks.bookname": {
"value": "*Iron-Man*"
}
}
},
{
"term": {
"salesbooks.soldout": {
"value": false
}
}
}
]
}
}
}
It should be empty as I want filter salesbooks.bookname contain ("iron-man") and soldout is false, it didn't work
can I know what's wrong inside
Thank you

Answer 1

The "must" clause requires that all clauses be true, in your case there is no "salesbooks.bookname": "Iron-Man" and soldout false, only "salesbooks.bookname": "Iron-Man" and soldout true.
Another important point is that the wildcard is a Term Level Query.
My example I tested (I figured salesbooks is a nested object).
PUT /house
{
"mappings": {
"properties": {
"salesbooks": {
"type": "nested",
"properties": {
"bookname": {
"type": "keyword"
},
"soldout": {
"type": "boolean"
}
}
}
}
}
}
PUT /house/_doc/1
{
"shopname": "seven up",
"shopkeeper": "John",
"salesbooks": [
{
"bookid": 11,
"bookname": "Tom-story",
"soldout": false
},
{
"bookid": 12,
"bookname": "Iron-Man",
"soldout": true
}
]
}
GET house/_search
{
"from": 0,
"query": {
"nested": {
"path": "salesbooks",
"query": {
"bool": {
"must": [
{
"wildcard": {
"salesbooks.bookname": "*Iron-Man*"
}
},
{
"term": {
"salesbooks.soldout": {
"value": true
}
}
}
]
}
}
}
}
}
