* Add some missing documentation.
* Adjust some documentation due to breaking changes.
* Adjust structure of documentation for easier changelog rendering and
browsing.
This extension currently ships with Elasticsearch integration which is
enabled by default. This behaviour is kept for backwards compatibility.
Still you now have the possibility to disable this integration in
extension manager, just check the "disable" box for elasticsearch.
In the future elasticsearch will become another extension and no default
is shipped with search_core. But for now, as we are still in alpha /
beta phase we keep things together to keep development fast.
Resolves: #111
As TypoScript does not provide a way to configure key less options, we
use a comma separated list and explode them to stay compatible with
elasticsearch.
* To support further configuration, specific to identifiers / tables.
* E.g. mapping and boost configuration should be possible.
* Adjust docs and settings.
* Adjust tests and code.
