Search Invoices for Visible Comments

SOLVED

Hi all,

We use the visible comment field in invoices to add information about sales- things like "Hold Invoice" for items we are holding, or "One Repack" for invoices that have partial cases of a particular item. 

Is there a way to search through these comments to find all invoices containing specific words?

In the Invoice Detail Report I tried using the filter, but it seems like the data field "comment line 1" does not find my terms. 

Anyway to do this?
