基于whoosh实现的flask全文搜索插件


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

from flask_msearch import Search
[...]
search = Search()
search.init_app(app)

# models.py
class Post(db.Model):
    __tablename__ = 'post'
    __searchable__ = ['title', 'content']

# views.py
@app.route("/search")
def w_search():
    keyword = request.args.get('keyword')
    results = search.whoosh_search(Post,query=keyword,fields=['title'],limit=20)
    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)

# 创建
search.create_index()
# 更新
search.create_index(update=True)
# 删除
search.create_index(delete=True)

如果只想要为指定的表创建索引

search.create_index(Model)

自定义analyzer

比如使用jieba的中文分词

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

Configure

WHOOSH_BASE = 'whoosh_index'
WHOOSH_ENABLE = True
