I have found a workaround for my problem, so I am answering my own question. Maybe this workaround could be useful to someone.

To obtain same result of the following code:

meta = {}
meta['name'] = '{$regex: /p1/}'
p1 = kbi.db.query(Pose._type, {}, meta, True, [], {}, 0)

I used the approach of:

1. Asking ROSPlan all object types existing in the domain.
2. After that I used types together name to query the DB until I have a result.

Of course, this approach is not best approach as it makes a lot of queries to the DB, but it works.

res = services['get_domain_types']()
for type_name in res.types:
    instance = db.query_named('%s__%s' % (type_name, item_name), return_type)
    if instance is not None:
        return instance, type_name

I am answering my own question again, this is happening so many times... :-) Although it could seem that I am writing questions too quick, I spent several time trying to fix this situation four months ago. So, it seems that asking here my question is helping me to think about the problem from other perspective.

I have found a workaround for my problem, so I am answering my own question. Maybe this workaround could be useful to someone.someone but it only works with 'ROSPlan' and not direct requests to 'mongodb_store' package.

This code is part of rosplan_interface package.
