Hi,
If this is already answered, please point me to the thread. TIA for that.
Now, the problem:
I am having the following code to test MultiSearchRequest{Buuilder} and it
always throws me NullPointerException (even if I just use matchAllQuery()
in the SearchRequests added to it).
public void performMultiSearchQuery () {
Client client = new TransportClient().addTransportAddress(new
InetSocketTransportAddress("localhost", 9300));
SearchRequestBuilder srb1 = client.prepareSearch()
.setQuery(QueryBuilders.queryString("sev:1")).setSize(Integer.MAX_VALUE);
SearchRequestBuilder srb2 = client.prepareSearch()
.setQuery(QueryBuilders.queryString("priority:50")).setSize(Integer.MAX_VALUE);
MultiSearchResponse sr = client.prepareMultiSearch()
.add(srb1.request())
.add(srb2.request())
.execute().actionGet();
// You will get all individual responses from
MultiSearchResponse#getResponses()
long nbHits = 0;
for (MultiSearchResponse.Item item : sr.getResponses()) {
SearchResponse response = item.getResponse();
nbHits += response.getHits().getTotalHits();
}
logger.info("Total Number of Hits: " + nbHits);
client.close();
}
And the exception it throws is:
Exception in thread "main"

I have searched my best and you might notice that the above code is the
sample snippet from ES doc page. Please help me in figuring out what the
issue is.
P.S:- Individually both those SearchRequestBuilders are working fine.
Best,
V. Varadhan
