How do I combine elasticsearch filter queries with OR using the Java API - elasticsearch

Question

I have these fields:
country (can be "DK", "US", "UK" and so on)
media ("book", "ebook", "cd")
state ("active", "inactive")
I would like to search for all documents that have country="DK" AND ((media="book" AND state="inactive") OR (media="ebook" AND state="ACTIVE)
I am creating a BoolQueryBuilder like this:
BoolQueryBuilder bqb = QueryBuilders
.boolQuery()
.must(QueryBuilders.termsQuery("country", "DK"));
bqb.filter(QueryBuilders.termsQuery("media", "book"));
bqb.filter(QueryBuilders.termsQuery("state", "inactive");
NativeSearchQuery searchQuery = new NativeSearchQueryBuilder()
.withQuery(bqb)
.build();
From what I can understand from this Stackoverflow question: elasticsearch bool query combine must with OR I should create a query looking like this:
{
"query": {
"bool": {
"must": [
{
"term": {"country": "DK"}
},
{
"bool": {
"should": [
{
"bool": {
"must": [
{"term": {"media": "book"}},
{"term": {"state": "inactive"}}
]
}
},
{
"bool": {
"must": [
{"term": {"media": "ebook"}},
{"term": {"state": "active"}}
]
}
}
]
}
}
]
}
}
}
Is this correct?
How do I do this with the Java API?

Answer 1

After some trial and error this seems to work:
BoolQueryBuilder bqb = QueryBuilders
.boolQuery()
.must(QueryBuilders.termsQuery("country", "DK"));
BoolQueryBuilder query1 = QueryBuilders.boolQuery();
query1.filter(QueryBuilders.termsQuery("media", "book"));
query1.filter(QueryBuilders.termsQuery("state", "inactive");
BoolQueryBuilder query2 = QueryBuilders.boolQuery();
query2.filter(QueryBuilders.termsQuery("media", "ebook"));
query2.filter(QueryBuilders.termsQuery("state", "active");
bqb.filter(QueryBuilders.boolQuery().should(query1).should(query2));
NativeSearchQuery searchQuery = new NativeSearchQueryBuilder()
.withQuery(bqb)
.build();
And it generated this query:
{
"bool" : {
"must" : [
{
"terms" : {
"country" : [
"DK"
],
"boost" : 1.0
}
}
],
"filter" : [
{
"bool" : {
"should" : [
{
"bool" : {
"filter" : [
{
"terms" : {
"media" : [
"book"
],
"boost" : 1.0
}
},
{
"terms" : {
"state" : [
"inactive"
],
"boost" : 1.0
}
}
],
"adjust_pure_negative" : true,
"boost" : 1.0
}
},
{
"bool" : {
"filter" : [
{
"terms" : {
"media" : [
"ebook"
],
"boost" : 1.0
}
},
{
"terms" : {
"state" : [
"active"
],
"boost" : 1.0
}
}
],
"adjust_pure_negative" : true,
"boost" : 1.0
}
}
],
"adjust_pure_negative" : true,
"boost" : 1.0
}
}
],
"adjust_pure_negative" : true,
"boost" : 1.0
}
}
