The box over the grid reads Search and filter. It narrows the rows the same way the Products list in your Shopify admin does.
Search
Type a word and press Enter. Variants and products are found by the product's name, the variant's name and the SKU; every word you type must be found, at the start of a word. An order is found by its number, "1001", with or without the #.
Filters
Pick a filter from the list, then a value from your store.
- Variants and products: Vendor, Tag, Type, Collection.
- Orders: Payment status, Fulfillment status, Date placed (today, the last 7 days, the last 30 days).
A filter can be "is" or "is not". Several filters narrow together.
Nothing found
A search that finds nothing offers Clear search and filters.
The search travels with you
A CSV export holds the rows the grid lists under the current search and filters, not the whole store. Clear them first to export everything. See Exporting and importing a CSV file.
Orders show the last 60 days
The Orders grid lists orders placed in the last 60 days. An older order is not listed and cannot be searched for.
