# Making a product in-stock & out of stock filter

Product stock status in WooCommerce is stored in the **\_stock\_status** private custom field, which can have two values: *instock* and *outofstock*

On the search instance *Frontend Search Settings -> Custom field filters* panel you can easily make a filter on this field:

..this will result in:

## Detailed Instructions

* To the *Custom Field* input enter: *\_stock\_status*
* In this example I use the Radio type, but Checkboxes or Drop-down is just as good
* To the values textarea enter:

  ```
  ||Any value**
  instock||In stock
  outofstock||Out of stock
  ```
