Hm I haven't heard of this term before but it sounds like it. The filters are additive, which means you reduce the result further by adding more filters. You can for example filter for a tag, add a group to filter for authors and then search through the remaining articles by text search.

I haven't found this feature to be that useful all the time, depending on the amount of articles you have. This is why it won't be in the new UI on day one (but will be re-implemented later, the backend is still there). You can find almost anything by using a few keywords, which is how I navigate Emvi right now.

[Edit] We have the plan to add configurable dashboard filters, which use the filters to show a subset of all articles, tags, members, groups and lists you like. I guess that's closer to what you described.
