Depending on the search box you use, there are different rules which govern each. For example in some you may input the second part of a customers name (eg Smith) but the search box needs the beginning of the name (which you may not recall off hand). Then, in the Assign Invoices search box you are given a universal drop-down list instead of being able to enter the invoice number or client name etc to refine your search - Come on Kashflow, this is pretty basic stuff!
