数据库搜索语法错误

Question

我正在通过web2py创建一个产品评论网站，并且在添加搜索功能时遇到了困难。这是我到目前为止的代码：

def index():
rows = db(db.reviews).select()

name_default = request.vars.name
body_default = request.vars.body
objects_default = request.vars.objects

form = SQLFORM.factory(
            Field("Item Name", default = name_default),
            Field("Body", default = body_default),
            Field("Objects", default = objects_default),
            formstyle = 'divs'
            submit_button = "Search"
            )

query = db.db1.id_user == auth.user_id

if form.process().accepted:
    name = form.vars.name
    body = form.vars.body
    objects = form.vars.objects

count = db(query).count()
results = db(query).select(orderby=~db.db1.data)
msg = T("%s registers" % count)
return dict(form=form, msg=msg, results=results)

return locals()

我得到的错误是第23行28字符（submit_button = "Search"行）的语法错误。
