这里直接利用代码讲述，代码中有详细的注释

利用的是elasticsearch_dsl.FacetedSearch，多面查询，重写特定的方法，达到目的

代码如下

from django.conf import settings
from elasticsearch_dsl.query import Query
from elasticsearch_dsl import Document, Keyword, Text, FacetedSearch, Short, Q, TermsFacetclass ArticleDocument(Document):kind = Short()author = Keyword()keyword = Keyword(multi=True)title = Text(analyzer="ik_smart", search_analyzer="ik_smart", fields={'name': Keyword()})context = Text(analyzer="ik_smart", search_analyzer="ik_smart", fields={'name': Keyword()})class Index:name = 'articles'settings = {"number_of_shards": settings.PAGE,}class ArticleSearch(FacetedSearch):index = 'articles'doc_types = ArticleDocumentfields = ['title', 'keyword', 'context']# 聚合设置，根据关键字author聚合# 关键子author，不能是Text类型，否则会触发异常，状态码400，异常信息illegal_argument_exception# 可以提供多个聚合关键字facets = {'author': TermsFacet(field='author')}def __init__(self, query=None, filters={}, sort=(), extra_query=None, page=1):""":param query::param filters::param sort::param extra_query: 额外查询条件，原始的查询条件是query包含于fields指定的字段:param page: 分页，指的是第几页"""self.page = pageself.extra_query = extra_querysuper().__init__(query, filters, sort)def query(self, search, query):if query:if self.fields:query_ = Q('multi_match', fields=self.fields, query=query)else:query_ = Q('multi_match', fields=self.fields, query=query)if isinstance(self.extra_query, Query):query_ = query_ & self.extra_queryreturn search.query(query_)return searchdef build_search(self):s = super().build_search()# 返回分页结果，这里是10个结果为一页，也是系统默认的return s[settings.PAGE * (self.page - 1):self.page * settings.PAGE]
