+Breacking Change 120 "Pass facets configuration to Elasticsearch"
+=================================================================
+
+In order to allow arbitrary facet configuration, we do not process the facet configuration anymore.
+Instead integrators are able to configure facets for search service "as is". We just pipe the
+configuration through.
+
+Therefore the following, which worked before, does not work anymore:
+
+.. code-block:: typoscript
+   :linenos:
+   :emphasize-lines: 4
+
+    plugin.tx_searchcore.settings.search {
+        facets {
+            category {
+                field = categories
+            }
+        }
+    }
+
+Instead you have to provide the full configuration yourself:
+
+.. code-block:: typoscript
+   :linenos:
+   :emphasize-lines: 4,6
+
+    plugin.tx_searchcore.settings.search {
+        facets {
+            category {
+                terms {

+                }
+            }
+        }
+    }
+
+You need to add line 4 and 6, the additional level ``terms`` for Elasticsearch.
+
+See :issue:`120`.

+Feature 131 "Pages do not get indexed if content has changed"
+=============================================================
+
+Previously we only used DataHandler hooks triggered when processing records. This way we did not
+index a page when content has changed.
+
+We now also use cache clear hooks of DataHandler to index pages whenever their cache get cleared.
+This way we also index a page if an integrator configured to clear further pages if content was
+changed.
+
+Still there are limitations. We do not get informed for pages which got cleared due to attached
+caches via TypoScript.

+Breacking Change "Introduce PHP 7.0 TypeHints"
+==============================================
+
+As PHP evolved, we now migrate the whole code base to use PHP 7.0 type hints.
+We do not use PHP 7.1 Type Hints, as some customers still need PHP 7.0 support.
+
+Also we added missing methods to interfaces, that were already used in code.
+
+As this leads to changed method signatures, most custom implementations of interfaces, or overwrites
+of existing methods are broken.
+
+To fix, just update the signatures as pointed out by PHP while running the code.

+FEATURE 25 "Respect multiple languages" - Provide sys_language_uid
+==================================================================
+
+Previously we did not fetch ``sys_language_uid`` field from database. This prevented everyone from
+working with multiple languages.
+By not removing the field it gets indexed and provides a very basic way of implementing multiple
+languages.
+At least it's now possible to filter search results by current language for now. Still the records
+are not "valid" as we do not add overlays for now.
+
+This is a first step into full multi language support.
+
+Martin Hummer already has a basic proof of concept, based on :ref:`concepts_dataprocessing` working,
+depending on ``sys_language_uid``.
+
+See :issue:`25`.

 Concepts
 ========
 
-The extension is built with the following concepts in mind.
+The main concept is to provide a foundation where other developers can profit from, to provide
+integrations into search services like Elasticsearch, Algolia, ... .
+
+Our code contains the following concepts which should be understand:
 
 .. _concepts_connections:
 
 Connections
 -----------
 
-It should be possible to use different search services like elasticsearch and solr out of the box.
-If a service is not contained, it should be possible to implement the necessary part by implementing
-the necessary interfaces and configuring the extension to use the new connection.
+Different search services can provide integrations. ``search_core`` only provides abstractions and
+interfaces. The main purpose is to provide a stable API between TYPO3 and concrete connection.
 
-Also it should be possible to use multiple connections at once. This way multiple search services
-can be used in the same installation.
-
-Currently only :ref:`Elasticsearch` is provided.
+For information about implementing a new connection, take a look at :ref:`development_connection`.
 
 .. _concepts_indexing:
 
 Indexing
 --------
 
-The indexing is done by one of the available indexer. It should be possible to define the indexer to
-use for certein document types. Also it should be possible to write custom indexer to use.
+Indexing is the process of collecting and preparing data, before sending it to a Connection.
+The indexing is done by one of the available indexer. Indexer are identified by a key, as configured
+in TypoScript.
 
-Currently only the :ref:`TcaIndexer` is provided.
+Currently :ref:`TcaIndexer` and :ref:`PagesIndexer` are provided.
+
+For information about implementing a new indexer, take a look at :ref:`development_indexer`.
+
+.. _concepts_dataprocessing:
+
+DataProcessing
+^^^^^^^^^^^^^^
+
+Before data is transfered to search service, it can be processed by "DataProcessors" like already
+known by :ref:`t3tsref:cobj-fluidtemplate-properties-dataprocessing` of :ref:`t3tsref:cobj-fluidtemplate`.
+The same is true for retrieved search results. They can be processed again by "DataProcessors" to
+prepare data for display in Templates or further usage.
+
+This should keep indexers simple and move logic to DataProcessors. This makes most parts highly
+flexible as integrators are able to configure DataProcessors and change their order.
+
+Configuration is done through TypoScript, see :ref:`dataprocessors`.
+
+For information about implementing a new DataProcessor, take a look at :ref:`development_dataprocessor`.

+
+This will create a ``month`` filter with sub properties. To make this filter actually work, you

+
+    mapping {
+        filter {
+            month {
+                type = range

+

+                }
+            }
+        }
+    }
+
+``fields`` has a special meaning here. This will actually map the properties of the filter to fields
+in Elasticsearch. On the left hand side is the Elasticsearch field name, on the right side the one
+submitted as a filter.
+
+The ``field``, in above example ``released``, will be used as the Elasticsearch field for
+filtering. This way you can use arbitrary filter names and map them to existing Elasticsearch fields.
+
+Everything that is configured inside ``raw`` is passed, as is, to search service, e.g.
+Elasticsearch.

+This is necessary if you have configured special mapping for some fields, or just want to search
+some fields. The following is an example configuration::
+
+    fields {
+        query = _all, city
+    }
+
+The following sub properties configure the fields to fetch from Elasticsearch:
+
+First ``stored_fields`` which is a list of comma separated fields which actually exist and will be
+added. Typically you will use ``_source`` to fetch the whole indexed fields.
+
+Second is ``script_fields``, which allow you to configure scripted fields for Elasticsearch.
+An example might look like the following::
+
+    fields {
+        script_fields {
+            distance {
+                condition = {request.filter.distance.location}
+                script {
+                    params {
+                        lat = {request.filter.distance.location.lat -> f:format.number()}
+                        lon = {request.filter.distance.location.lon -> f:format.number()}
+                    }
+                    lang = painless
+                    inline = doc["location"].arcDistance(params.lat,params.lon) * 0.001
+                }
+            }
+        }
+    }
+
+In above example we add a single ``script_field`` called ``distance``. We add a condition when this
+field should be added. The condition will be parsed as Fluidtemplate and is casted to bool via PHP.
+If the condition is true, or no ``condition`` exists, the ``script_field`` will be added to the
+query. The ``condition`` will be removed and everything else is submitted one to one to
+Elasticsearch, except each property is run through Fluidtemplate, to allow you to use information
+from search request, e.g. to insert latitude and longitude from a filter, like in the above example.
+
+.. _sort:

+
+Sort is handled like :ref:`fields`.
+
+.. _mode:
+
+mode
+----
+
+Used by: Controller while preparing action.

+Define to switch from search to filter mode.
+
+Example::
+
+    plugin.tx_searchcore.settings.searching {
+        mode = filter
+    }
+
+Only ``filter`` is allowed as value, as ``search`` is default behaviour. Using ``filter`` will
+trigger a search to provide data while visiting the page, possible :ref:`filter` allow you to build
+pages like "News".

+        1 = Codappix\SearchCore\DataProcessing\CopyToProcessor
+        1 {

+
+.. Of course you are able to provide further processors. Just implement

+
+.. By implementing also the same interface as necessary for TYPO3
+.. :ref:`t3tsref:cobj-fluidtemplate-properties-dataprocessing`, you are able to reuse the same code

+.. ``ObjectManager``.
