Java multi search result repetition

Elastic Stack Elasticsearch
1

When I use java multi search api 5.2.2, there are many duplicate data in the response. Is there any other api which can remove these duplicate data?

2

No. I'd not use multi search in such a case

Maybe I didn't describe clearly. For example:

qb1 = QueryBuilders.queryStringQuery("key");
SearchRequestBuilder srb1 = client.prepareSearch()
                    .setQuery(qb1).setIndices(indexName)
                    .setTypes(type).setSize(size);
qb2 = QueryBuilders.matchQuery("resourceType", "user");
SearchRequestBuilder srb2 = client.prepareSearch()
                    .setQuery(qb2).setIndices(indexName)
                    .setTypes(type).setSize(size);
MultiSearchResponse sr = client.prepareMultiSearch().add(srb1).add(srb2).get();

In fact, result has one hit, but there are two in the response.

Why won't you use a Boolean Query here instead then?

Is there any example or docs about boolean query?

Yes:

https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-compound-queries.html#java-query-dsl-bool-query

Can this method add query dynamically? Such as:

if(!key.equals("")){
    qb1 = QueryBuilders.queryStringQuery(key);
}
QueryBuilder qb = QueryBuilders.boolQuery();
qb.must(qb1);
8

I'd write:

BoolQueryBuilder qb = QueryBuilders.boolQuery();

if (!key.equals("")) {
    qb.must(QueryBuilders.queryStringQuery(key));
}

It will report error that can't resolve method must.:neutral_face:
