最近学校老师让我们自己学习搜索引擎用python语言的，自己网上查了很多，但还是有问题。如下
__init__.py
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)

# 配置 sqlalchemy  数据库驱动://数据库用户名:密码@主机地址:端口/数据库?编码
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:123456@localhost:3306/BYSJ?charset=utf8'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = True
app.config['WHOOSH_BASE'] = 'path/to/whoosh/base'

# 初始化
db = SQLAlchemy(app)

models.py
from jieba.analyse.analyzer import ChineseAnalyzer
import flask_whooshalchemyplus
from __init__ import db, app

class filemessage(db.Model):
__tablename__ = 'filemessage'
__searchable__ = ['title', 'content']
__analyzer__ = ChineseAnalyzer()
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.Unicode)
content = db.Column(db.Text)

flask_whooshalchemyplus.init_app(app)

view.py
from flask import render_template, request
from flask_bootstrap import Bootstrap
from flask_whooshalchemyplus import index_all
from __init__ import *
from models import filemessage
app = Flask(__name__)
bootstrap = Bootstrap(app)

@app.route('/')
def home():
index_all(app)
return render_template('search_results.html')

@app.route('/search', methods=['GET'])
def search_results():
query = request.args.get('search')
results = filemessage.query.whoosh_search(query).all()
return render_template('search_results.html', results=results)

if __name__ == '__main__':
app.debug = True
app.run()

#前端
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<div>
<form action="{{url_for('search')}}" method="get">
      <input type="text" placeholder="站内搜索" name="search" >
      <button type="submit">搜索</button>
   </form>
</div>
<div>
<ul>
{% for post in results %}
<li>
      <div>
         <div>
            {{ post.title }}
            {{ post.content }}
         </div>
      </div>
</li>
{% endfor %}
</ul>
</div>
</body>
</html>

错误如下：
