#JetBrains 六折贺新春!IntelliJ IDEA,PyCharm,WebStorm,PhpStorm 优惠!
你知道的,每次 Lucene 发布新版本时,Solr 也会相应发布更新版本。Lucene 刚刚发布了5.0 版本,Solr 也同时发布了 5.0 版本。从 5.0 开始 Solr 不再提供 war 包方式,而是以独立的 Java 服务器方式提供安装(小编个人不喜欢,至少应该保留 war 包,因为更方便于使用自己喜好的容器部署)。
Solr 5.0 的改进内容包括:
Improved bin/solr
and new bin/post
scripts
New, and restructured, example Config Sets available by default
SolrJ now has first class support for the Collections API
Implicit registration of /replication
, /get
, and /admin/*
request handlers
Scripts to support installing and running Solr as a service on Linux
Logging improvements :
Transaction log replay status is now logged
Optional logging of slow requests.
Config API that supports paramsets for easily configuring Solr parameters for request handlers and editing common solrconfig.xml
options.
New Blob Store API with support for uploading and distributing plugin jars.
Splitting of clusterstate to per-collection enables scalability improvement in SolrCloud
Distributed IDF Support
Option to configure max bandwidth usage by ReplicationHandler
pivot.facet
results can now include nested stats.field
results constrained by those pivots
stats.field
can be used to generate statistics over the results of arbitrary numeric functions
A new DateRangeField
has been added for indexing date ranges, especially multi-valued ones
Spatial fields that used to require units=degrees
now take distanceUnits=degrees/kilometers
miles instead
