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?

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

Maybe I didn't describe clearly. For example:

```auto
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:

Can this method add query dynamically? Such as:

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

```

</div>

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.😐
