The dictionary when filtering occurrences must be typed {Any,Any}

[tpoisot]

Because the paging system uses Int for the number of pages, offset, etc., the Dict containing the query must be typed appropriately. One solution would be to use Pairs (as in mangal filtering), which can also be passed using ... (and this would remove two methods for `occurrences at the cost of breaking the current code (but I can probably still use the dict and give a deprecation warning).
