google app engine OR filter

I want to do an OR filter within google app engine.

For example:

class MyModel(db.Model):
    name = db.StringPropery()
    description = db. StringPropery()

The following will return all "MyModel" instances with name = steve AND description = "some text"

results = MyModel.all().filter("name =", "steve").filter("description =","some text").fetch(10)

开发者_Go百科What syntax do I use to change this to an OR statement? Or do I need to do two queries and then merge them somehow?
