> In order to reduce space usage, unused indexes should be removed or trimmed. Trimmed,
because an index definition might contain "too much" (specially Lucene indexes, which index
multiple properties and can be very large).
> One solution is to 
> * log each query (avoiding duplicates), 
> * include which indexes were used,
> * from that generate the minimum index definitions,
> * compared with existing indexes, get the list of unused indexes and index features since
day X.
