"My expectation is that scanning Doc Values might be faster than inverted
index if a query matches more than %25 of documents."
I seriously doubt it. Or my expectations are really off base, which is
always possible, I confess I've never measured though. At a high
level:
indexed:
find entry for term_im_searching_for, read the list of IDs it
satisfies immediately
DocValues
if (doc1.val.equals(term_im_searching_for)) { add it to the list }
And if there was more than one clause you'd be scanning the DocValues
for each term.....
It'd be interesting to actually measure though.
