Appendix - Dynamic Fields¶
Dynamic fields allow you to add custom fields to Solr documents. That said, you never need to modify Solr’s schema (which could cause problems or at least unnecessary additional work when updating the Solr extension). The following sections describe how to use dynamic fields with your Solr for TYPO3 installation. Usage of dynamic fields
You can use dynamic fields by following a special naming convention for document fields. E.g. to create a dynamic field that is a string the field name should end with _stringS. So if you want to create a field for storing a title you would name it title_stringS. We suggest you use lower camel case for the field name followed by an underscore followed by the dynamic field type “extension”.
We’ve predefined the following dynamic fields:
