Multiple indices for a given model

[fabiociotoli]

I have two indices, ModelIndexA and ModelIndexB, both for same model (A is default).
In my settings I have:

...'INDICES': { 'index_a': 'package.index_a', 'index_b': 'package.index_b' }...

When the search_index --update is executed, just the default index is updated.
In both ModelIndex subclasses I redefined the matches_indexing_condition method and I saw that this is called just for default index.

Is there any workaround?
