Well from what you provided there are not any forms, but this is what you would want in a form. When you use the "Command Button" tool there is an option record navigation> find record, this will open a the Access Find and Replace dialog box which is a very simple way of doing it. It will allow you to search multiple fields but only one at a time.
If you wanted to search multiple fields at once you would need to create a form with a text box that would be your search word. Then create a query that searched all the multiple fields that you want to search with a "Criteria" of the value of that text box. Although since you want "or" you should probably put them all under one column. The build function will help you out on that.
Good luck.
