Vincent Newkirk cc44a4a28f Correct Documentation for lowerStrict/upperStrict (#6707)
The documentation for Bound filter's lowerStrict/upperStrict is incorrect. It is not consistent with the examples provided and actual behaviour of the bound filter. Correct this.

Gian Merlino 154b6fbcef SQL: Add "POSITION" function. (#6596)
Also add a "fromIndex" argument to the strpos expression function. There
are some -1 and +1 adjustment terms due to the fact that the strpos
expression behaves like Java indexOf (0-indexed), but the POSITION SQL
function is 1-indexed.

Jakub Kukul e2431ae161 Update defaultHadoopCoordinates in documentation. (#5720)
* Update defaultHadoopCoordinates in documentation.

To match changes applied in #5382.

* Remove a parameter with defaults from example configuration file.

If it has reasonable defaults, then why would it be in an example config file?

Also, it is yet another place that has been forgotten to be updated and will be forgotten in the future.

Also, if someone is running different hadoop version, then there's much more work to be done than just changing this property, so why give users false hopes?

* Fix typo in documentation.

the old page about theta sketches.

Gian Merlino ed47a1e1a9
Lookups: Inherit "injective" from registered lookups, improve docs. (#5316)
Code changes:
- In the lookup-based extractionFns, inherit injective property from
  the lookup itself if not specified.

Doc changes:
- Add a "Query execution" section to the lookups doc explaining how
  injective lookups and their optimizations work.
- Remove scary warnings against using registeredLookup extractionFns.
  They are necessary and important since they work with filters and
  function cascades -- two things that the dimension specs do not do.
  They deserve to be first class citizens.
- Move the "registeredLookup" fn above the "lookup" fn. It's probably
  more commonly used, so the docs read better this way.
