我能够使用elasticsearch Explain API为我的more like this查询结果获得解释。然而，我在python中无法实现同样的功能，因为显然explain不支持More like this。这是我尝试过的。

def execute_mlt_query(self, like_text, field, min_term_freq=1, min_doc_freq=1):
        s = Search(using=self.client, index=self.index_name)

        # Build the MLT query dynamically
        mlt_query = Q("more_like_this", fields=[field], like=like_text, min_term_freq=min_term_freq, min_doc_freq=min_doc_freq)

        s = s.query(mlt_query) 
        result = s.execute() 

        return self.get_docs_from_hits(result,mlt_query)

 def get_docs_from_hits(self, result, mlt_query):
        for hit in result:
            self.similar_documents.append({
                "doc_id": hit.meta.id,
                "score": hit.meta.score,
                "label": hit.to_dict()['yes'],
               
            })
            
              explanation = self.client.explain(self.client,  index=self.index_name, doc_type="_doc", id=hit.meta.id, body=mlt_query.to_dict())
            print(explanation)

但我得到了这个错误。

**raise HTTP_EXCEPTIONS.get（status_code，TransportError）（elasticsearch.exceptions.RequestError：请求错误（400，'parsing_exception'，'请求不支持[more_like_this]'）

这是我试图实现的，但在Python中，

import org.apache.lucene.search.Explanation;
import org.elasticsearch.action.explain.ExplainRequest;
import org.elasticsearch.action.explain.ExplainResponse;

ExplainRequest request = new ExplainRequest(ESQuery.index_name, "_doc", hit.getId());
request.query(QueryBuilders.moreLikeThisQuery(fields,texts,null).minTermFreq(1));
ExplainResponse response = client.explain(request, RequestOptions.DEFAULT);
Explanation explanation = response.getExplanation(); 
String exp_str = explanation.toString();
