flask 貌似很少全文搜索的插件,有一个 https://github.com/gyllstromk/Flask-WhooshAlchemy, 但试了几次都用不了,所以参考 Flask-WhooshAlchemy 自己写了一个

Quickstart

插件基于 whoosh,纯 python 编写,使用上很简单

 1from flask_msearch import Search
 2[...]
 3search = Search()
 4search.init_app(app)
 5
 6# models.py
 7class Post(db.Model):
 8    __tablename__ = 'post'
 9    __searchable__ = ['title', 'content']
10
11# views.py
12@app.route("/search")
13def w_search():
14    keyword = request.args.get('keyword')
15    results = search.whoosh_search(Post,query=keyword,fields=['title'],limit=20)
16    return ''

Usage

创建更新删除索引

如果要对已存在的数据创建索引(全部)

1# 创建
2search.create_index()
3# 更新
4search.create_index(update=True)
5# 删除
6search.create_index(delete=True)

如果只想要为指定的表创建索引

1search.create_index(Model)

自定义analyzer

比如使用jieba的中文分词

1from jieba.analyse import ChineseAnalyzer
2search = Search(analyzer=ChineseAnalyzer())

Configure

1WHOOSH_BASE = 'whoosh_index'
2WHOOSH_ENABLE = True
