Help on creating a search with a pasted list

I would love to have a text field on a page into which a user could paste a list of account numbers, then click a search button and have the model return only the records that have that account number in a specified field. I have an annoying process where I only get account numbers from a third party and I need to get full details on those accounts, mark them with a flagging field and notify users that these accounts need attention. Would it be possible to paste in a set of comma (or tab or enter) separated account numbers into a text field and search within those values to determine which records get returned in the query?

Excellent! Thanks, I’ll give it a go.
