Reduce the overall query complexity by fetching instances and shared instances separately. Apply filters (e.g. for readability) to each dataset instead of JOINing them and having multiple WHERE conditions. UNION the two datasets to get the final result set. On large foundations this reduces the query execution time from multiple 100ms to less than 100ms.
