Advanced development with eZ Find - part 2 : Indexing additional fields in Solr

Step 2 : Indexing year and year /month in Solr
eZ Find settings ( ezfind.ini, to be overridden in the ezfind.ini.append.php file of your extension ) allow for delegating the indexing process of an eZ Publish datatype to a given PHP class :
[SolrFieldMapSettings] CustomMap[ezdate]=ezfSolrDocumentFieldDate
Our PHP class, randomly named , ezfSolrDocumentFieldDate inherits from the ezfSolrDocumentFieldBase class, must be added to the /extension/myextension/classes folder and must inherit the following skeleton :
<?php
class ezfSolrDocumentFieldDate extends ezfSolrDocumentFieldBase
{
public static function getFieldName( eZContentClassAttribute $classAttribute, $subAttribute = null, $context = 'search' )
{
// return the fieldname like : attr_mydate_d
}
public function getData()
{
// return the array keys (fieldname => value), like : array('attr_mydate_dt' => '2010-04-30T00:00:00Z')
}
}
?>
