In booq POS you have the option to search for an article by going to 'Articles > products':

If you want to search for an article, you can enter the name or part of the name of the article in the field 'type to search', followed by enter
This will display all products that meet the search criteria

At 'Product group' click the dropdown menu, where the default is "all"
Press the down arrow of Product groups to display the underlying groups
Select the groups that you want to filter. Only the items in that product group will then be displayed

Click on "Filter" at the top right
You can use several filters simultaneously
Enter the criteria on which you want to filter
Click on "Apply Filters" at the bottom right
All articles that meet the criteria will then be displayed
If you have set up filters and want to delete them, click on the cross next to the filter or on "Filter" in the upper right corner and then on "Delete all filters" in the lower right corner
