+``Codappix\SearchCore\DataProcessing\ContentObjectDataProcessorAdapterProcessor``
+=================================================================================
+
+Will execute an existing TYPO3 data processor.
+
+Possible Options:
+
+``_dataProcessor``
+    Necessary, defined which data processor to apply. Provide the same as you would to call the
+    processor.
+``_table``
+    Defines the "current" table as used by some processors, e.g.
+    ``TYPO3\CMS\Frontend\DataProcessing\FilesProcessor``.
+
+All further options are passed to the configured data processor. Therefore they are documented at
+each data processor.
+
+Example::
+
+    plugin.tx_searchcore.settings.searching.dataProcessing {
+        1 = Codappix\SearchCore\DataProcessing\ContentObjectDataProcessorAdapterProcessor
+        1 {
+            _table = pages
+            _dataProcessor = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
+
+            references.fieldName = media
+            as = images
+        }
+    }
+
+The above example will create a new field ``images`` with resolved FAL relations from ``media``
+field.
