What version of Solr is required to implement Taxonomy?

To implement RChilli’s Taxonomy (Standardization/Taxonomy 3.0) effectively with Solr, there are specific system requirements, including the Apache Solr version. Based on the documentation and best practices provided by RChilli:

Required Solr Version for Taxonomy Implementation

Apache Solr version 7.x or higher is required to integrate and utilize RChilli’s Taxonomy features.

Why This Version Requirement Exists

1. Ontology & Faceted Search Compatibility: RChilli’s Taxonomy 3.0 uses ontologies and hierarchical classification that rely on modern Solr features like:

   • Dynamic fields

   • Faceting and filtering

   • Multi-language tokenization

   • Enhanced schema management

2. Performance & Scalability: Later versions of Solr (7.x and above) provide performance optimization necessary for real-time search and taxonomy-enhanced data indexing.

3. Search & Match Integration: RChilli’s Enhanced Search & Match API integrates with Solr to provide enriched search results using taxonomy. These features are built and tested with Solr environments starting from version 7.x and upwards.

Best Practice

• Ensure your Solr instance is updated to at least version 7.x, though version 8.x or later is recommended for optimal results and compatibility with other modern features like:

  • JSON request handlers

  • Streaming expressions

  • Schema-less configurations
