Subject [ANNOUNCE] Apache Solr 7.3.0 released
Date Wed, 04 Apr 2018 21:23:43 GMT
4th April 2018, Apache Solr™ 7.3.0 available

The Lucene PMC is pleased to announce the release of Apache Solr 7.3.0

Solr is the popular, blazing fast, open source NoSQL search platform from
the Apache Lucene project. Its major features include powerful full-text
search, hit highlighting, faceted search and analytics, rich document
parsing, geospatial search, extensive REST APIs as well as parallel SQL.
Solr is enterprise grade, secure and highly scalable, providing fault
tolerant distributed search and indexing, and powers the search and
navigation features of many of the world's largest internet sites.

This release includes the following changes since the 7.2.0 release:

- A new update request processor supports OpenNLP-based entity extraction
and language detection
- Support for automatic time-based collection creation
- Multivalued primitive fields can now be used in sorting
- A new SortableTextField allows both indexing and sorting/faceting on free
- Several new stream evaluators
- Improvements around leader-initiated recovery
- New autoscaling features: triggers can perform operations based on any
metric available from the Metrics API, based on a defined schedule, or in
response to a query rate over a 1-minute average. A new screen in the Admin
UI will show suggested autoscaling actions.
- Metrics can now be exported to Prometheus
- {!parent} and {!child} support filtering with exclusions via new local
- Introducing {!filters} query parser for referencing filter queries and
excluding them
- Support for running Solr with Java 10
- A new contrib/ltr NeuralNetworkModel class

Furthermore, this release includes Apache Lucene 7.3.0 which includes
several changes since the 7.2.0 release
