我们如何使用elastic search在django rest框架中获得热门搜索列表？

ELASTICSEARCH_HOST = 'localhost'
ELASTICSEARCH_PORT = 9200

from elasticsearch_dsl import Document, Text

class ArticleIndex(Document):
    title = Text()
    content = Text()

    class Index:
        name = 'articles'

python manage.py search_index --rebuild

from elasticsearch import Elasticsearch

def get_hot_search_list(request):
    keyword = request.GET.get('keyword', '')
    
    # 创建Elasticsearch客户端
    es = Elasticsearch([{'host': settings.ELASTICSEARCH_HOST, 'port': settings.ELASTICSEARCH_PORT}])
    
    # 在索引中搜索关键字
    search_results = es.search(index='articles', body={'query': {'match': {'title': keyword}}})
    
    # 处理搜索结果，获取热门搜索列表
    hot_search_list = [hit['_source']['title'] for hit in search_results['hits']['hits']]
    
    return hot_search_list
