Hi, I am thinking of implementing a
#CATQUERY <query>
magic keyword for the category pages.
When this keyword is present, the category page would execute a query
against the search backend instead of normal category behavior and show
result as if those pages were actually marked with this category.
For example, this would allow Greek Philosophers category page to be
quickly redefined as
a cross-section of greeks & philosophers categories:
#CATQUERY incategory:Greek incategory:Philosopher
Obviously the community will be able to define much more elaborate
queries,
including the ordering (will be supported by the
new search backend)

I like the idea in principle, but think the syntax could use bikeshedding ;)
If we use this as category pages, im a little worried that people could get
confused and try to add [[category:Greek philosophers]] to a page, and
expect it to work. We would need good error handling in that situation
Also, at least at first, you couldn't use one of these synthetic categories to filter
search results so you couldn't use them to build other synthetic categories.

Cool. I didnt realize search would support this. That's a pretty big deal
since people expect there categorirs alphabetized.
So I looked into it and it would be easy to implement with Cirrus _but_ I'm not yet
sure about the memory implications. We have a ton of headroom on memory now so it might
not matter but I need to test it before I can be as confident that it is ok as I was last
night at 1am. It may have caveats like synthetic categories must be less than 1000
articles or not all results are included.
Another cool project would be to expand intersection/Dyanamic P age List
(Wikimedia) to be able to use search as a different backend (however, that
extension would need quite a bit of refactoring to get there)
