Kirill Kozlov 9f93be448e Fix logical operator in example (#3093) 2016-06-07 10:44:18 -07:00
Gian Merlino 1853f36e9f More consistent empty-set filtering behavior on multi-value columns. 
The behavior is now that filters on "null" will match rows with no
values. The behavior in the past was inconsistent; sometimes these
filters would match and sometimes they wouldn't.

Adds tests for this behavior to SelectorFilterTest and
BoundFilterTest, for query-level filters and filtered aggregates.

Fixes #2750.

Gian Merlino ff25325f3b Improved docs for multi-value dimensions. 
- Add central doc for multi-value dimensions, with some content from other docs.
- Link to multi-value dimension doc from topN and groupBy docs.
- Fixes a broken link from dimensionspecs.md, which was presciently already
  linking to this nonexistent doc.
- Resolve inconsistent naming in docs & code (sometimes "multi-valued", sometimes
  "multi-value") in favor of "multi-value".
