An OR relationship is if you want all records that have a particular Hotel name, or else have a particular Client name. (Assuming these are the 2 fields you need to handle... for my B&S it was Contractor & Location). It's the union of the 2.
I don't think the lack of the OR relationship was what brought the points down. I think it is that it is annoying to have to enter an exact name, especially if you are a bad speller
If I was going to enhance the UI, I would add an Exact Match check mark next to each text field. By default, it would be off, but users could turn it on. (That is to meet the requirements that we provide an Exact Match capability).
Or, you could provide a copy/paste capability within the table, so you could copy from a table cell into the text field. That didn't work on mine... well it sorta worked, except that the copy from the table cell returned data for the whole row, which is not exactly what you want to paste in.
Finally, I think I read about someone who got all the unique Names and Locations from the database and then allowed the user to pick from a combo box for these fields.
