Is there a way to do a Count() query in ImageVault 4

Hi,

Is there any way in ImageVault 4(.7) to do some sort of 'COUNT' query using the ImageVault API?
We've implemented paging by using the 'Skip' and 'Take' implementations as described here: http://imagevault.se/en/documentation/api-documentation/?page=csharp/examples/querying-mediaitems/querymedia.html and this seems to work properly.
Now we would also like to know the total amount of items found when not using paging. The only way I found to do it is to fetch all items and do a 'Count()' on the fetched collection.
Is their a proper way of doing it using the ImageVault API?

Regards,

Robert.

I don't think it's possible.

One thing we've done a few times when needing better querying and searching capabilities is regularly exporting MediaItem objects to Find.

As you write you can do a count on the fetched items. But you can't get that information without fetching them first.

You can however query statistics for specific vaults and get information about number of items in that vault.

Thanks for your replies! Querying for Vault statistics seems usefull, however we need statistics based on one or more categories.

To get the number of items for categories you will need to fetch the items for that category/categories first and then do a count.
