I am using Elasticsearch maven jar file to query Elasticsearch. But now I want to query the elasticsearch using full generated query string:
query :
{
"bool" : {
"must" : [ {
"term" : {
"title" : "mercedes"
}
}, {
"term" : {
"Doors" : "2"
}
} ]
}
}
How do I use the above query string to query elasticsearch in java?
Following code prepares a boolquery. You should create a SearchRequestBuilder to execute it.
BoolQueryBuilder boolQuery = new BoolQueryBuilder();
boolQuery.must(QueryBuilders.termQuery("title", "mercedes"));
boolQuery.must(QueryBuilders.termQuery("Doors", "2"));
If you want to use query as string without building it in code, you can use following;
String myQuery = "Your Query Here";
SearchSourceBuilder ssb= new SearchSourceBuilder();
search.query(myQuery);
SearchRequestBuilder srb; // You should define srb before next steps
srb.internalBuilder(ssb);
SearchResponse response = srb.execute().actionGet();
I use the following code to query Elasticsearch using JSON string.
SearchResponse response = client.prepareSearch(yourIndexName)
.setSource(yourJsonQueryString)
.execute().actionGet();
