Hum… We tried it once, and it seemed to work. But when we tried cross-repository export/import of documents bearing such properties they were not accepted any more.
It will not help you much, but I think what you're trying to do is not possible.
Anyway, if you find a solution I'm interested by a clue.

Can you be a bit more specific? These documents should be going into Alfresco and they won't be imported into any other Alfresco we didn't set up. I'm not sure I understand the problem.

Could you elaborate on the limitations of doing this?

A map is not a dictionary type. It is correctly managed by Alfresco as long as it is a Serializable value, but if you export it in an ACP it cannot be reimported because it becomes considered as a string.
Did you try ACP export/import of your documents ?

So how would you structure a query to search on a map entry?

I don't know !
But I wanted to warn you about this approach. You may manage to index your map properties correctly in Lucene but I expect you'll have other problems, for instance the import/export behaviour.
