# Searching by Lists of Values

You can search by a list of certain values of the following license attributes:

- License number.

- GUID.

  Note that searching by lists supports only GUIDs of types HWID and PA HWID.

- Activation code.

The difference of this kind of search from the search described in Custom Search Query is that lists of values are stored in Partner Central and can be reused.

The search by lists works in the following way. After you have specified a list of values, it is saved automatically on the server and is assigned an ID. Partner Central then automatically creates a custom search query using the `list` parameter. The `list` parameter takes the list’s ID as a value. For example, `list:3`.

Using the search by lists allows running corresponding queries many times without the need to specify a list of values each time. Also, it enables users to easily share a search query.

The owner of a list (the user who created this list) can view and update the list. The updated list is saved as a new list with another ID. Other users can only perform the search by typing `list:<` id `>` in the search box.

If a list is not used for 90 days, it is removed.

To create a list of values and search by this list:

1. On the Manage Licenses tab, open the menu under the plus icon (to the right of the search box), and click Search by List of Licenses.

2. Type the values in the Search by List of Licenses form. Do not specify the “list” word. Values should either start on a new line, or be separated by a semicolon, tab stop, space, or comma.

   If you search by license numbers, you can type a full number or just its middle part. Zeros in the beginning can be omitted. For example, to search for PLSK.02320288.0007, type either of the following: PLSK.02320288.0007, PLSK.02320288, 02320288, 2320288.

   Example of a list of license numbers:

       PLSK.02869885.0001 PLSK.02869692.0001 PLSK.02869682.0001

3. Click Search.

4. Partner Central will display a list of licenses that were found. It will also save the list. In the search box, it will display a search query that contains the ID of the created list (`list:<` id `>)`.

   Remember the ID if you are going to use this query again. You can share this query with other users, so that they do not create duplicate queries.

To modify a list of values:

If you are the creator of the list with the ID <id of your list>, you can modify this list, or, to be more exact, create a new list based on the existing list. Creation of a new list prevents the functionality of the initial list being lost.

1. On the Manage Licenses tab, enter `list:` <id of your list> in the search box `.`
2. Open the menu under the plus icon (to the right of the search box), and click Search by List of Licenses. The contents of the list with the specified ID will appear.
3. Modify the list and click Search.
4. Partner Central will display a list of licenses that were found. It will also save the list with another ID. In the search box, it will display a search query that contains the ID of the list (`list:<` id `>)`.
