query search select columns from registered model

[henryorton]

Is it possible to search only within select columns of the registered model. Say you have:

@whooshee.register_model('title', 'content')
class Entry(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String)
    content = db.Column(db.Text)

It would be great if I could only search content column by:

Entry.query.whooshee_search('chuck norris', fields=('content',)).all()

Or is it possible to do this by registering a custom woosheer? I can't quite figure out how to be able to search both 'title' and 'content', while also being able to search only 'title' or 'content' separately.

So I found that I can make a custom whoosheer to only search the 'content' column as below. However this seems to create a separate index from the original registered model. This seems a little inefficient or is that how these full text searches work? Is there something I'm missing?

@whooshee.register_whoosheer
class ContentWhoosheer(AbstractWhoosheer):
    schema = whoosh.fields.Schema(
        entry_id = whoosh.fields.NUMERIC(stored=True, unique=True),
        content = whoosh.fields.TEXT())

    models = [Entry]

    @classmethod
    def update_entry(cls, writer, entry):
        writer.update_document(entry_id=entry.id,
                               content=entry.content)

    @classmethod
    def insert_entry(cls, writer, entry):
        writer.add_document(review_id=review.id,
                               content=entry.content)

    @classmethod
    def delete_entry(cls, writer, entry):
        writer.delete_by_term('entry_id', entry.id)
