PyMISP.search does not allow searching for attributes with first_seen as None

[emuradov]

I would like to search for attributes that do not have a set first_seen value (value set to None).

When using the PyMISP search functions as follows:
pymisp.search(controller='attributes', first_seen=None)

The returned results are all attributes. If any integer value is supplied that's not a period such as '24h', then all the attributes WITH a first_seen value are returned.

Is there a way to search for attributes ONLY with a first_seen value of None? Can this be implemented if not available now? Also if possible, the args first_seen and last_seen should be added to the documentation under the search function as they do work.

None is discarded on PyMISP side. I'm pretty sure MISP is also discarding searching for None, but I'll let one of my colleagues answer on that point (cc @iglocska @righel @mokaddem).

If that is implemented on MISP side, we need to come up with a generic approach for such search requests because they cannot be the default, and might end-up returning crazy amount of data.

Is there any plan in the future to allow such querying? It would be helpful to quickly segment data.

Hi... Will this request move forward or should we furgetaboutit? :)
