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.indexing``.
.. _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:
Indexing
^^^^^^^^
Holds settings regarding the indexing, e.g. of TYPO3 records, to search services.
Configured as::
plugin {
tx_searchcore {
settings {
indexing {
identifier {
indexer = FullyQualifiedClassname
// the settings
}
}
}
}
}
Where ``identifier`` is up to you, but should match table names to make :ref:`TcaIndexer` work.
The following settings are available. For each setting its documented which indexer consumes it.
.. _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.indexing.<identifier>.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.indexing.<identifier>.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.
.. _mapping:
``mapping``
"""""""""""
Used by: Elasticsearch connection while indexing.
Define mapping for Elasticsearch, have a look at the official docs: https://www.elastic.co/guide/en/elasticsearch/reference/5.2/mapping.html
You are able to define the mapping for each property / columns.
Example::
plugin.tx_searchcore.settings.indexing.tt_content.mapping {
CType {
type = keyword
}
}
The above example will define the ``CType`` field of ``tt_content`` as ``type: keyword``. This
makes building a facet possible.
.. _configuration_options_search:
Searching
^^^^^^^^^
.. _facets:
``facets``
"""""""""""
Used by: Elasticsearch connection while building search query.
Define aggregations for Elasticsearch, have a look at the official docs: https://www.elastic.co/guide/en/elasticsearch/reference/5.2/search-aggregations-bucket-terms-aggregation.html
Currently only the term facet is provided.
Example::
plugin.tx_searchcore.settings.searching.facets {
contentTypes {
field = CType
}
}
The above example will provide a facet with options for all found ``CType`` results together
with a count.
.. _boost:
``boost``
"""""""""
Used by: Elasticsearch connection while building search query.
Define fields that should boost the score for results.
Example::
plugin.tx_searchcore.settings.searching.boost {
search_title = 3
search_abstract = 1.5
}
