TYPO3 optimized Solr Index Schema
A schema definition file comes with EXT:solr. Using this schema ensures an index optimized for TYPO3 content. Additionally a set of dynamic fields are defined allowing to dynamically add more fields as needed without having to modify the schema definition.
It is planned to provide a mechanism to detect and inform about differences in the used schema and the recommended schema shipping with the extension. This will be especially useful should the schema change when upgrading to a newer version of the extension.
Schema changes can become necessary due to changes in TYPO3 as well as Apache Solr. Especially Apache Solr usually comes with new, more optimized field types with each release.
