Err, I'm more than a little surprised that code works.
* Sphinx is fine with a single array of values, but not arrays within
arrays
* Sphinx can't (yet) filter on strings. That's upcoming in 0.9.10,
apparently.
The following syntax is fine:
Tree.search 'sapling', :with => {:variety => [1, 2, 3]}
But I wouldn't expect this one to work reliably:
Tree.search 'sapling', :with => {:variety => 'pine redwood'}
Let alone your more complex example...
From a Sphinx API perspective, you can't send through arrays of
arrays, or strings, when it comes to filters. So, if you're getting
the right results, I'd personally put it down to some fluke in Sphinx.
Don't make any assumptions on this working for production sites.
