Flask-Whoosh is a small Flask extension to make manipulating Whoosh indexes a bit more convenient in the context of a Flask web application.

Features:

• ability to create indexes without having to pre-create the parent folder
• manages a pool of reusable Whoosh search objects
• provides easy access to a Whoosh AsyncWriter, allowing web applications to simply modify the index and commit without worrying about other requests interfering.

from flask import Flask
from flask_whoosh import Whoosh
from whoosh.fields import TEXT

app = Flask(__name__)
app.config.from_pyfile('config.py')
fw = Whoosh(app)

Later on:

from whoosh.query.qcore import Every
with app.app_context():
    results = fw.searcher.search(Every())    

Install the packages listed in requirements-test.txt, and then run

nosetests --with-coverage --cover-package=flask_whoosh

Or if you want nice reporting:

nosetests --with-spec --spec-color --with-coverage --cover-package=flask_whoosh
