python - Django ElasticSearch 仅返回 10 个行集

Question

我在我的 django 应用程序中使用 ElasticSearch-DSL，查询仅返回 10 行。当我使用尺寸时。我收到错误“multi_match”查询不支持大小。

from django.shortcuts import render
from elasticsearch_dsl import Q
from elasticsearch_dsl.query import MultiMatch
# Create your views here.
from search.documents import CarDocument
from products.models import Products

def search(request):
   q = request.GET.get('q')
   if q:
       #cars = CarDocument.search().query("match", model_name=q)
      q = request.GET.get('q', None)
      query1 = MultiMatch(query=q,  fields=['product_make', 'bodystyle','model_name','variant','transmission','yom'])
      s = CarDocument.search().query(query1)
      cars = s.execute()
   else:
      cars = ''

   return render(request, 'search/search.html', {'cars': cars})

Answer 1

这样，您将获得所有记录：

s = CarDocument.search().query(query1)
total = s.count()
s = s[0:total]
cars = s.execute()

Answer 2

默认情况下，它返回 10 个数据。如果你想要超过 10 个数据，比如获得 50 个数据，你可以使用CarDocument.search()[:50]
