Do not implement feature with custom code, but use existing feature to
create search_abstract field.
Also execute DataProcessing in AbstractIndexer, not in TcaTableService,
to affect all current available indexers, not only some.
Also this is the place to be.
Add functional test to test facet configuration including:
- Mapping (indexing)
- Searching (retrieving of facets)
- Filter (already existed, now based on facet case sensitive)
* 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.
* Add typoscript option which TYPO3 tables should be processed and which
should not be processed.
* Respect new optiion in hook.
* Also add necessary tests.
* Remove old no longer needed tests for hook.
