Patch looks good!  One less query relying on TermsEnum caching...

> SpanFilters are inefficient and OOM easily (they don't scale at all: Create large Lists
of Objects for every match, also filtering deleted docs is a pain). Some talks with Grant
on Eurocon and also the fact that caching of them is still broken in 3.x (but fixed on trunk)
- I assume nobody uses them, so let's nuke them. They are also in wrong package, so standard
statement: "Die, SpanFilters, die!"
