whoosh search after database migration - database

Question

I migrated my database from sqlite3 to postgresql with the following three steps
I create a sqlite dump file with
sqlite3 app.db .dump > app_dump.sql
I create a postgresql database and initialized it with my models.py file as
python manage.py db init
where manage.py is
SQLALCHEMY_DATABASE_URI = 'postgresql+psycopg2://appuser:777#localhost/app_db'
migrate = Migrate(app, db)
manager = Manager(app)
manager.add_command('db', MigrateCommand)
if __name__ == '__main__':
manager.run()
I used only the insert lines in the dump file to populate the new database.
This worked well, however I do want to have a whoosh search in my User table.
My models.py looks like this
if sys.version_info >= (3, 0):
enable_search = False
else:
enable_search = True
import flask.ext.whooshalchemy as whooshalchemy
class User(db.Model):
__searchable__ = ['username','id']
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(100), index=True)
if enable_search:
whooshalchemy.whoosh_index(app, User)
However, the search does not seem to work at all. I fear that the table has not been properly indexed? Anybody know how I can fix this?
thanks

By default flask_whooshalchemy indexes a record when the sqlalchemy session commits. So if you want to index all non-indexed-data you can try my fork which is called flask_whooshalchemyplus see the manually indexing introduction.
