When you're working in a register, you can use the search feature to filter information.
Simply click in the search field, which is located in the top left corner of any register window, and type what you want to search for. For example, if you type the number for a check, QuickBooks will find that check for you. If you search for a payee, QuickBooks will show you all the transactions with that payee. Besides the check number and payee, you can also filer by type of transaction, account, memo, date, and amount.
QuickBooks is pretty literal. If you type “12” in the search field, you’ll get transactions from December, from 2012, and with 12 in the amount, among other things. If you want to search for transactions dated in December, and your dates appear as mm/dd/yy, you could type “12/” in the search field.
Note: You can only search for information that is visible in the register. QuickBooks will not filter by information in splits or any other form details that aren't visible in the register.
Note: You set how the date appears in your register (and elsewhere) using Mac OS X System Preferences > Language & Region.
