Lucene PMC 宣布发布了 Apache Lucene 7.1.0 和 Apache Solr 7.1.0

Lucene可从http://www.apache.org/dyn/closer.lua/lucene/java/7.1.0下载  
Solr可从http://www.apache.org/dyn/closer.lua/lucene/solr/7.1.0下载

Lucene的更新亮点包括：

• New Geo3D shapes for non-spherical planet models

• Serialization and deserialization support for Geo3D

• A new CoveringQuery, whose required number of matching clauses can be defined per document

• New BengaliAnalyzer for Bengali language

• A point based range field called LatLonBoundingBox

• FloatPointNearestNeighbor, an N-dimensional FloatPoint K-nearest-neighbor search implementation

• Faster default taxonomy cache

• Support for computing facet counts for individual numeric values via LongValueFacetCounts

• Faster geo-distance queries in case of dense single-valued fields when most documents match

• Better heuristics in IndexOrDocValuesQuery

• Optimized builds for OrdinalMap (used by SortedSetDocValuesFacetCounts and others)

Solr的更新亮点包括：

• Critical Security Update: Fix for CVE-2017-12629 which is a working 0-day exploit reported on thepublic mailing list.

• Auto-scaling: Solr can now move replicas automatically when a new node is added or an existing node is removed using the auto scaling policy framework introduced in 7.0

• Auto-scaling: The 'autoAddReplicas' feature which was limited to shared file systems is now available for all file systems. It has been ported to use the new autoscaling framework internally.

• Auto-scaling: New set-trigger, remove-trigger, set-listener, remove-listener, suspend-trigger, resume-trigger APIs

• Auto-scaling: New /autoscaling/history API to show past autoscaling actions and cluster events

• New JSON based Query DSL for Solr that extends JSON Request API to also support all query parsers and their nested parameters

• JSON Facet API: min/max aggregations are now supported on single-valued date fields

• Lucene's Geo3D (surface of sphere & ellipsoid) is now supported on spatial RPT fields by setting spatialContextFactory="Geo3D". Furthermore, this is the first time Solr has out of the box support for polygons

• Expanded support for statistical stream evaluators such as various distributions, rank correlations, distances and more.

• Multiple other optimizations and bug fixes
