Instructions:

When searching any pane in Master, a message stating "x-number of invoices found. The search might take several minutes. Do you want to cancel the search?"
If pressing No, the search results are returned. If pressing Yes, the search results are not returned.

It is possible to increase the limit of the number of invoices for when this message is given. This is done from IP Admin:

1. Navigate to IP Admin - System administration --> Configuration --> Parameters
2. Find the parameter called RESULT COUNT, by pressing "Add" and finding it in the drop down menu.
3. Increase the value of the parameter and save. Please note that it should not be set too high, as this might affect system performance.
