Translate REST call to Java API

Elastic Stack Elasticsearch
1

Hi,

I'm having a hard time converting a REST call to the JAVA equivalent,
the exact REST call is:

curl -XGET http://192.168.0.100:9200/inventory/_search?pretty=true -d
'
{
"query" : {
"query_string" : {
"fields" : ["part_number", "category",
"description"],
"query" : "Ac Adapter"
}
}

}
'

but I would really love to "learn" how to do it myself.

Thanks

Diego

First you need the querybuilder:

QueryStringQueryBuilder qsqb = QueryBuilders.queryString("Ac
Adapter").field("part_number", 1).field("category",
1).field("description", 1);

Then you need to set the query:
SearchRequestBuilder srb =
client.prepareSearch("inventory").setQuery(qsqb);

Now you can add facets or set the filter:
srb.addFacet();srb.setFilter();

As a last step you need to execute the query and fetch it / or add a
listener to it ...
srb.execute().actionGet();srb.execute().addListener();

Regards,
Peter.

Hi All,

How to search specific text using elastic search in java

this is my code..

Settings settings = ImmutableSettings.settingsBuilder()
.put("http.enabled", "false")
.put("transport.tcp.port", "9300-9400")
.put("discovery.zen.ping.multicast.enabled", "false")
.put("discovery.zen.ping.unicast.hosts", "localhost").build();

      Node node =

NodeBuilder.nodeBuilder().client(true).settings(settings).clusterName("elasticsearch").node();
client = node.client();

    QueryBuilder queryBuilder = QueryBuilders.termQuery("userName",

"SampleUser");
SearchRequestBuilder searchRequestBuilder =
client.prepareSearch("_river");
searchRequestBuilder.setTypes("dc_user_river");
searchRequestBuilder.setSearchType(SearchType.DFS_QUERY_AND_FETCH);
searchRequestBuilder.setQuery(queryBuilder);
searchRequestBuilder.setFrom(0).setSize(60).setExplain(true);
SearchResponse resp = searchRequestBuilder.execute().actionGet();
System.out.println(resp);
for (SearchHit hit : resp.getHits())
System.out.println("Hit ID: "+hit.getId());
node.close();

output :
{
"took" : 32,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}

When starting a new discussion on a mailing list, please do not reply to
an existing message, instead start a fresh email. Even if you change the
subject line of your email, other mail headers still track which thread
you replied to and your question is "hidden" in that thread and gets less
attention. It makes following discussions in the mailing list archives
particularly difficult
