Django实现搜寻性能
1、在Django配置搜寻后果页的路由映射
"""pachong URL ConfigurationThe `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/1.10/topics/http/urls/Examples:Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: url(r'^/pre>, views.home, name='home')Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: url(r'^/pre>, Home.as_view(), name='home')Including another URLconf 1. Import the include() function: from django.conf.urls import url, include 2. Add a URL to urlpatterns: url(r'^blog/', include('blog.urls'))"""from django.conf.urls import urlfrom django.contrib import adminfrom app1 import viewsurlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^/pre>, views.indexluoji), url(r'^index/', views.indexluoji), url(r'^suggest//pre>, views.suggestluoji,name="suggest"), # 搜寻字段补全申请 url(r'^search//pre>, views.searchluoji,name="search"), # 搜寻]2、编写逻辑处理函数
在逻辑处理函数里实现搜寻数据
（1）获取到用户的搜索词
（2）利用原生的elasticsearch(搜索引擎)接口，实现搜寻，注明：elasticsearch-dsl就是在原生的elasticsearch上做了封装
Elasticsearch()办法，连贯原生的elasticsearch服务器
search()办法，原生elasticsearch查询方法，反对原生的elasticsearch查问语句，返回的原生语句后果也就是字典模式的数据
在查问语句里进行关键词高亮解决
将查问到的后果，循环获取到后返回到html页面
from django.shortcuts import render# Create your views here.from django.shortcuts import render,HttpResponsefrom django.views.generic.base import Viewfrom app1.models import lagouType # 导入操作elasticsearch(搜索引擎)类import jsonfrom elasticsearch import Elasticsearch # 导入原生的elasticsearch(搜索引擎)接口client = Elasticsearch(hosts=["127.0.0.1"]) # 连贯原生的elasticsearchdef indexluoji(request): print(request.method) # 获取用户申请的门路 return render(request, 'index.html')def suggestluoji(request): # 搜寻主动补全逻辑解决 key_words = request.GET.get('s', '') # 获取到申请词 re_datas = [] if key_words: s = lagouType.search() # 实例化elasticsearch(搜索引擎)类的search查问 s = s.suggest('my_suggest', key_words, completion={ "field": "suggest", "fuzzy": { "fuzziness": 1 }, "size": 5 }) suggestions = s.execute_suggest() for match in suggestions.my_suggest[0].options: source = match._source re_datas.append(source["title"]) return HttpResponse(json.dumps(re_datas), content_type="application/json")def searchluoji(request): # 搜寻逻辑解决 key_words = request.GET.get('q', '') # 获取到申请词 response = client.search( # 原生的elasticsearch接口的search()办法，就是搜寻，能够反对原生elasticsearch语句查问 index="lagou", # 设置索引名称 doc_type="biao", # 设置表名称 body={ # 书写elasticsearch语句 "query": { "multi_match": { # multi_match查问 "query": key_words, # 查问关键词 "fields": ["title", "description"] # 查问字段 } }, "from": 0, # 从第几条开始获取 "size": 10, # 获取多少条数据 "highlight": { # 查问关键词高亮解决 "pre_tags": ['<span class="keyWord">'], # 高亮开始标签 "post_tags": ['</span>'], # 高亮完结标签 "fields": { # 高亮设置 "title": {}, # 高亮字段 "description": {} # 高亮字段 } } } ) total_nums = response["hits"]["total"] # 获取查问后果的总条数 hit_list = [] # 设置一个列表来贮存搜寻到的信息，返回给html页面 for hit in response["hits"]["hits"]: # 循环查问到的后果 hit_dict = {} # 设置一个字典来贮存循环后果 if "title" in hit["highlight"]: # 判断title字段，如果高亮字段有类容 hit_dict["title"] = "".join(hit["highlight"]["title"]) # 获取高亮里的title else: hit_dict["title"] = hit["_source"]["title"] # 否则获取不是高亮里的title if "description" in hit["highlight"]: # 判断description字段，如果高亮字段有类容 hit_dict["description"] = "".join(hit["highlight"]["description"])[:500] # 获取高亮里的description else: hit_dict["description"] = hit["_source"]["description"] # 否则获取不是高亮里的description hit_dict["url"] = hit["_source"]["url"] # 获取返回url hit_list.append(hit_dict) # 将获取到内容的字典，增加到列表 return render(request, 'result.html', {"all_hits": hit_list, "key_words": key_words}) #显示页面和将列表和搜索词返回到html3、html页面接管搜寻后果
留神：因为Django实现了避免恶意代码写入，但凡通过变量传输到html页面的html类型代码，将会被主动转换成字符串形式显示，索引咱们须要在接管变量的字段用：{% autoescape off %} {{ 接管变量 }} {% endautoescape %}，来显示html代码，
搜寻后因为进行了一次跳转，所以搜寻框里的搜索词将不存在，咱们须要在传递搜寻后果到页面的时候，将搜索词也传递进来填充到搜索框
