要在java中实现一个有三级父子关系的嵌套搜索,相关资料很少,发在stackoverflow上以后一个Switzerland的大神很快回复了我,google+stackoverflow很好使。对应的命令行query:
{
"query": {
"has_child": {
"type": "instance",
"query": {
"has_child": {
"type": "instance_permission",
"query": {
"terms": {
"uuid": {
"index": "user",
"type": "user",
"id": "5",
"path": "uuids"
}
}
}
}
}
}
}
}
java api:
TermsLookupQueryBuilder terms = QueryBuilders
.termsLookupQuery("uuid")
.lookupIndex("user")
.lookupType("user")
.lookupId("5")
.lookupPath("uuids");
HasChildQueryBuilder hQuery = QueryBuilders
.hasChildQuery("instance", QueryBuilders
.hasChildQuery("instance_permission", terms));
System.out.println("Exectuing Query 1");
System.out.println(hQuery.toString());
SearchResponse searchResponse1 = client
.prepareSearch("foo_oa_hr_askforleave")
.setQuery(hQuery).execute().actionGet();
System.out.println("There were " + searchResponse1.getHits().getTotalHits()
+ " results found for Query 1.");
System.out.println(searchResponse1.toString());
System.out.println();
