returns nothing no mater what keyword

Hi, I just modified my code following the instruction of QuickStart and Config, like this

@course.route("/search")
def w_search():
    keyword = request.args.get('q')
    results = Course.query.msearch(keyword,fields=['title']).first()
    return redirect(url_for('course.classes', id=results.id))

However it returns nothing no mater what keywords did I miss some other configurations? actually, I know nothing about the role of Create_index

Thanks a Lot For Your Help!!!

>>> Course.query.msearch('asdf',fields=['title']).all()
[]
>>> Course.query.filter_by(title='asdf').all()
[<Course u'asdf'>]

@AdamGold current_user isn’t model instance, you should use current_user._get_current_object()

Thanks for reply @honmaple! I’m new to full-text search space, so please be adaptive on my idiocy.

If I understand correctly, analyzer returns tokens and if token (or their variable sum) is not a whole query, then search fails?

Example in your last example, say query was ch, while non of tokens have exact token:

print([token.text for token in ana("Opentech")])
# ['Ope', 'pen', 'ent', 'nte', 'tec', 'ech']

Then what added benefit is there over using: results = <Model>.query.filter(<Model>.<column>.ilike(f'%{q}%')).all() - where q is a query.

which is case insensitive search for substrings in Model column. Is it performance? Or am I misunderstanding tokenization on whoosh part?
