I would like to retrieve documents by the presence of an string in a nested array. For example, the data (representing a dependency parse of a sentence) looks like:
{'tuples': [['xcomp', 'multiply', 'using'],
['det', 'method', 'the'],
['nn', 'method', 'foil'],
['dobj', 'using', 'method']]}
The closest solution I've found assumes that ['nn', ...] is the second position of the tuples list-of-lists:
db.c.find({'tuples.2.0' : 'nn'})
Is there a way to relax the fixed position? The tuples (not their contents) can be in any order.
Secondly, it would be really great to be able to retrieve documents that have ['nn', 'method', X], meaning a noun "method" in their dependency parse.
Thank you!
