J'ai la structure json suivante dans elastic search qui est stockée @ http://localhost:9200/mongoindex/documents/
:
{
"text" : "OTesting1"
"otag" : "otag1"
"pages" : [{
"text" : "1"
"name" : "itag1"
}, {
"text" : "2"
"name" : "itag2"
}
]
}
J'ai créé un mapping imbriqué comme suit pour activer la recherche imbriquée et le filtre imbriqué sur celui-ci :
http://localhost:9200/mongoindex/documents/_mapping [PUT]
{
"documents": {
"properties": {
"pages": {
"type": "nested"
}
}
}
}
Maintenant, exécutez le code java suivant :
Settings settings = ImmutableSettings.settingsBuilder()
.put("cluster.name", "xyz").build();
Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9300));
SearchResponse response = client.prepareSearch("mongoindex")
.setTypes("documents")
.setQuery(QueryBuilders.nestedQuery("documents", QueryBuilders.boolQuery().must(QueryBuilders.matchQuery("pages.text", "1"))).scoreMode("avg"))
.execute()
.actionGet();
mais il me donne l'exception suivante :
> Exception in thread "main"
> org.elasticsearch.action.search.SearchPhaseExecutionException: Failed
> to execute phase [query], total failure; shardFailures
> {[kSKaBxjGTMSS352kukrYVw][mongoindex][0]:
