Maybe there is a way to have permalinks for indexes?
At the moment it's not possible to link to indexes as the node IDs will change and thus the links will not work anymore after an index rebuild. Maybe there is a way that indexes can be referenced by URLs that don't change? I'm not sure, but I think it might be possible to use something like this:
IndexInstanceNode instances by their
index_template_node_id.index attribute and
This way we could have permalinks to indexes that survive a rebuild.
