如何在我的django项目中使用elasticsearch？

pip install elasticsearch

ELASTICSEARCH_DSL = {
    'default': {
        'hosts': 'localhost:9200'  # Elasticsearch主机地址和端口
    },
}

from django_elasticsearch_dsl import Document, fields
from django_elasticsearch_dsl.registries import registry
from .models import YourModel

@registry.register_document
class YourModelDocument(Document):
    field1 = fields.TextField()
    field2 = fields.KeywordField()

    class Index:
        name = 'yourmodel_index'  # 索引名称

    def get_queryset(self):
        return YourModel.objects.all()

python manage.py search_index --rebuild

from elasticsearch_dsl import Search
from .documents import YourModelDocument

def search(request):
    q = request.GET.get('q')  # 获取搜索关键字
    s = Search().filter('term', field1=q)  # 在field1字段中搜索关键字
    response = s.execute()

    results = []
    for hit in response:
        results.append(hit)

    return render(request, 'search_results.html', {'results': results})
