The second, traditional way of constructing queries is as follows:
>>> from tinydb import where
>>> db.search(where('field') == 'value')
Using where('field') is a shorthand for the following code:
>>> db.search(Query()['field'] == 'value')
Accessing nested fields with this syntax can be achieved like this:
>>> db.search(where('birthday').year == 1900)
>>> db.search(where('birthday')['year'] == 1900)
