from Flask_SQLalchemy_Whoosh.searcher import WhooshSearcher
from Flask_SQLalchemy_Whoosh.mixin import SearchableMixin
from whoosh.fields import ID, TEXT, NUMERIC


app = Flask(__name__)

class Product(SearchableMixin, db.Model):
    __tablename__ = "product"
    # __searchable__ is needed to tell the searcher what to index
    # For documentation on the specifics of each field, refer to the Whoosh documentation
    # https://whoosh.readthedocs.io/en/latest/schema.html
    __searchable__ = {
        "id": ID(stored=True, unique=True),

        "desc": TEXT,
        "price": NUMERIC
    }

    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String),
    desc = db.Column(db.String),
    price = db.Column(db.Integer)


# If you want to index a table that  already has entries, use the reindex method
# It will index all entries in the table
Product.reindex()

# Use the search method to search a table
results, total = Product.search("name", "nails")
