Apache Solr 9.11.0 Adds New Options for Numeric Range Queries

Apache Solr, an open source search platform built on Apache Lucene, released version 9.11.0 on October 4, 2026. The release introduces changes aimed at improving how applications represent and query structured data.

More expressive numeric ranges

One of the release highlights is the addition of integer, long, float and double range field types. These can help applications represent numeric intervals and query records according to bounded values rather than treating every value as an isolated point.

The release also introduces an experimental numeric range query parser. As an experimental feature, it should be evaluated carefully against an application's requirements and tested before being used in critical production workflows.

Improvements to nested documents

Solr 9.11.0 also extends support for nested and block documents. Updates to parent and child query parsers can derive relevant filters from document paths, reducing the need for applications to specify internal nested paths manually.

These capabilities may be useful for systems that search complex records, including product catalogs, technical documentation, organizational data and content with hierarchical relationships.

What developers should consider

Teams planning an upgrade should review the official release notes, test queries against representative datasets and benchmark performance before changing production environments. Search behavior, indexing requirements and compatibility should be verified as part of the deployment process.

For publishers and knowledge platforms, structured search remains a key foundation for fast discovery, filtering and increasingly sophisticated retrieval experiences.
