Configuration
=============

The extension offers the following configuration options through TypoScript. If you overwrite them
through `setup` make sure to keep them in the `module` area as they will be accessed from backend
mode of TYPO3. Do so by placing the following line at the end::

    module.tx_searchcore < plugin.tx_searchcore

.. todo::

   We will use references inside the extension to make the above unnecessary in the future.

The structure is following TYPO3 Extbase conventions. All settings are placed inside of::

    plugin.tx_searchcore.settings

Here is the example default configuration that's provided through static include:

.. literalinclude:: ../../Configuration/TypoScript/constants.txt
   :language: typoscript
   :linenos:
   :caption: Static TypoScript Constants

.. literalinclude:: ../../Configuration/TypoScript/setup.txt
   :language: typoscript

.. _configuration_options:

Options
-------

The following section contains the different options, e.g. for :ref:`connections` and
:ref:`indexer`: ``plugin.tx_searchcore.settings.connection`` or
``plugin.tx_searchcore.settings.index``.

.. _configuration_options_connection:

connections
^^^^^^^^^^^

Holds settings regarding the different possible connections for search services like Elasticsearch
or Solr.

Configured as::

    plugin {
        tx_searchcore {
            settings {
                connections {
                    connectionName {
                        // the settings
                    }
                }
            }
        }
    }

Where ``connectionName`` is one of the available :ref:`connections`.

The following settings are available. For each setting its documented which connection consumes it.

.. _host:

``host``
""""""""

    Used by: :ref:`Elasticsearch`.

    The host, e.g. ``localhost`` or an IP where the search service is reachable from TYPO3
    installation.

    Example::

        plugin.tx_searchcore.settings.connections.elasticsearch.host = localhost

.. _port:

``port``
""""""""

    Used by: :ref:`Elasticsearch`.

    The port where search service is reachable. E.g. default ``9200`` for Elasticsearch.

    Example::

        plugin.tx_searchcore.settings.connections.elasticsearch.port = 9200


.. _configuration_options_index:

index
^^^^^

Holds settings regarding the indexing, e.g. of TYPO3 records, to search services.

Configured as::

    plugin {
        tx_searchcore {
            settings {
                indexer {
                    indexerName {
                        // the settings
                    }
                }
            }
        }
    }

Where ``indexerName`` is one of the available :ref:`indexer`.

The following settings are available. For each setting its documented which indexer consumes it.

.. _allowedTables:

``allowedTables``
"""""""""""""""""

    Used by: :ref:`TcaIndexer`.

    Defines which TYPO3 tables are allowed to be indexed. Only white listed tables will be processed
    through Command Line Interface and Hooks.

    Contains a comma separated list of table names. Spaces are trimmed.

    Example::

        plugin.tx_searchcore.settings.indexer.tca.allowedTables = tt_content, fe_users

.. _rootLineBlacklist:

``rootLineBlacklist``
"""""""""""""""""""""

    Used by: :ref:`TcaIndexer`.

    Defines a blacklist of page uids. Records below any of these pages, or subpages, are not
    indexed. This allows you to define areas that should not be indexed.
    The page attribute *No Search* is also taken into account to prevent indexing records from only one
    page without recursion.

    Contains a comma separated list of page uids. Spaces are trimmed.

    Example::

        plugin.tx_searchcore.settings.index.tca.rootLineBlacklist = 3, 10, 100

Also it's possible to define some behaviour for the different document types. In context of TYPO3
tables are used as document types 1:1. It's possible to configure different tables. The following
options are available:

.. _additionalWhereClause:

``additionalWhereClause``
"""""""""""""""""""""""""

    Used by: :ref:`TcaIndexer`.

    Add additional SQL to where clauses to determine indexable records from the table. This way you
    can exclude specific records like ``tt_content`` records with specific ``CType`` values or
    something else. E.g. you can add a new field to the table to exclude records from indexing.

    Example::

        plugin.tx_searchcore.settings.index.tca.tt_content.additionalWhereClause = tt_content.CType NOT IN ('gridelements_pi1', 'list', 'div', 'menu')

    .. attention::

        Make sure to prefix all fields with the corresponding table name. The selection from
        database will contain joins and can lead to SQL errors if a field exists in multiple tables.
