MLT using the Java API

Elastic Stack Elasticsearch
4

Hello.

I've tried to use MoreLikeThisRequestBuilder with Java API and there was
always no hit, the code as follows:

    MoreLikeThisRequestBuilder mlt = new

MoreLikeThisRequestBuilder(client, "aaa", "bbb", "1");
mlt.setField("title");
SearchResponse response =
client.moreLikeThis(mlt.request()).actionGet();

and I searches your solution, that is using MoreLikeThisQueryBuilder. but
It doesn't work, either. My codes are:

    MoreLikeThisQueryBuilder query = QueryBuilders.moreLikeThisQuery(); 
    query.boost(1.0f).likeText("title").minTermFreq(10);

   SearchResponse searchResponse =

client.prepareSearch("aaa").setTypes("bbb")
.setQuery(query)
.execute()
.actionGet();

is there something wrong with the searchResponse part? could you give me
some suggestions?
Thanks in advance!

Thanks Vineeth.

I got it working in the end. I changed the implementation to use a
MoreLikeThisQueryBuilder instead.

How many documents are there in the index ?

Try
.minTermFreq(0)
.minDocFreq(0))

I'm trying to get the MLT feature working via the Java API, here is my
request:

SearchResponse searchResponse =
client.moreLikeThis(moreLikeThisRequest(index).type(type)
.id(1)
.fields("text")
.minTermFreq(1)
.minDocFreq(1))
.actionGet();

I've made sure that document 1 and other documents in the index contain
the word "chicago" in the text field, but it is always returning zero hits.

The 'text' field is indexed and has "term_vectors:true"

Am I missing something here?
