In some cases - Virtual Cabinet may not be able to find certain documents. I.e. it can find some but not others.
The issue here is caused by the maximum number of results returned by Virtual Cabinet. The default is 1000 documents, meaning that FuseDocs can only find the first 1000 documents meaning that it cannot find certain documents past this number.
The resoluton for this is to increase the number of documents returned by Virtual Cabinet returned by search.
As the Virtual Cabinet Admin. Go to Admin > Global Settings > Set the Max search results to 5000.
