Hi Rinshin! If you're searching for a recipe title as a complete phrase and entering it in quotation marks -- "Better Than A-1 Marinade" -- then the system will search for and retrieve the exact phrase you entered, including "A-1" with the hyphen. But if you leave out the quotes and just enter that same string of words, you'll retrieve recipes entitled "Better than A-1 marinade" and "Better than A.1 steak marinade" (this is in the EYB Library/Recipes; results in a search of your Bookshelf will depend on the books/blogs/recipes you've added).
By the way, if that recipe appears in your copy of the May/Jun 2007 issue of Cook's Illustrated with the word "steak" in the title and not the way we've indexed it, let me know and I'll make the correction.
