Apache Solr 企业级全文搜索引擎
Solr是一个独立的企业级搜索应用服务器，它对外提供类似于Web-service的API接口。用户可以通过http请求，向搜索引擎服务器提交一定格式的XML文件，生成索引；也可以通过Http Get操作提出查找请求，并得到XML格式的返回结果；
Apache Solr 4.10.3 发布，该版本修复了 21 个 bug，同时修复了 Lucene 4.10.3 中的 12 个 bug 。
Bug 修复：
SOLR-6696: bin/solr start script should not enable autoSoftCommit by default
(janhoy)
SOLR-6704: TrieDateField type drops schema properties in branch 4.10
(Tomás Fernández Löbbe)
SOLR-6679: Remove suggester component from stock solrconfig.xml since it caused long startup times on lage indexes even when it wasn't used.
(yonik)
SOLR-6662: better validation when parsing command-line options that expect a value
(Timothy Potter)
SOLR-6705: Better strategy for dealing with JVM specific options in the start scripts; remove -XX:+AggressiveOpts and only set -XX:-UseSuperWord for Java 1.7u40 to u51.
(Uwe Schindler, janhoy, hossman, Timothy Potter)
SOLR-6738: Admin UI - Escape Data on Plugins-View
(steffkes)
SOLR-6085: Suggester crashes when prefixToken is longer than surface form
(janhoy)

(Adair Kovac, Joel Bernstein)
SOLR-6684: Fix-up /export JSON.
(Joel Bernstein)
SOLR-6732: Fix handling of leader-initiated recovery state was String in older versions and is now a JSON map, caused backwards compatibility issues when doing rolling upgrades of a live cluster while indexing
(Timothy Potter)

(David Smiley)
SOLR-6784: BBoxField's 'score' mode should have been optional.

(Christine Poerschke, David Smiley)
SOLR-2927: Solr does not unregister all mbeans upon exception in constructor causing memory leaks.
(tom liu, Sharath Babu, Cyrille Roy, shalin)
SOLR-6685: ConcurrentModificationException in Overseer Status API.
(shalin)
SOLR-6706: /update/json/docs throws RuntimeException if a nested structure contains a non-leaf float field
(Noble Paul, shalin)
SOLR-6610: Slow startup of new clusters because ZkController.publishAndWaitForDownStates always times out.
(Jessica Cheng Mallet, shalin, Noble Paul)
SOLR-6726: better strategy for selecting the JMX RMI port based on SOLR_PORT in bin/solr script
(Timothy Potter)

SOLR-6796: distrib.singlePass does not return correct set of fields for multi-fl-parameter requests.
(Per Steffensen via shalin)
