I want to filter by merchant for either expenses or receipts.
Hello! You can search for merchants from the Expenses page in your account on the Expensify website. Along the top of the page, you'll see the option to apply filters to your expenses view:
You can use this search box to pull up any expenses that use a specific merchant. If you don't see expenses that you know exist in your account, be sure to adjust the date range filter to see older expenses.
