When viewing the results of a smart query in Altru one will notice they only receive the first 500 records. In order to see the additional records beyond 500 you must export to excel. However, when you export it to excel you still only receive 500 records.
We are currently evaluating this issue and will update this article when we have more information.
Workaround: If possible try and recreate the Smart Query in a regular Ad-hoc query.
