How to make a selection using faceted search?

Question

Sphinx

Hello. Guided by this faceted search demo, I tried to repeat it for my project with some changes. In this example, you can select several categories at once, and the array will contain all rows that contain, for example, categories 10 and 11 (for example, 10 11 12, 11 12 13 and the like). How to set a condition in order to select only those rows where there are categories 10 and 11 (for example, 10 11 12, 10 11 13)? This effect can be achieved if you use all the filters to reduce the number of options.
Thanks
