<!--
索引存储方案，共有以下存储方案
1、solr.StandardDirectoryFactory,这是一个基于文件系统存储目录的工厂，它会试图选择最好的实现基于你当前的操作系统和Java虚拟机版本。
2、solr.SimpleFSDirectoryFactory,适用于小型应用程序，不支持大数据和多线程。
3、solr.NIOFSDirectoryFactory,适用于多线程环境，但是不适用在windows平台（很慢），是因为JVM还存在bug。
4、solr.MMapDirectoryFactory,这个是solr3.1到4.0版本在linux64位系统下默认的实现。它是通过使用虚拟内存和内核特性调用
mmap去访问存储在磁盘中的索引文件。它允许lucene或solr直接访问I/O缓存。如果不需要近实时搜索功能，使用此工厂是个不错的方案。
5、solr.NRTCachingDirectoryFactory,此工厂设计目的是存储部分索引在内存中，从而加快了近实时搜索的速度。
6、solr.RAMDirectoryFactory,这是一个内存存储方案，不能持久化存储，在系统重启或服务器crash时数据会丢失。且不支持索引复制
<directoryFactoryclass="${solr.directoryFactory:solr.NRTCachingDirectoryFactory}"name="DirectoryFactory">
<strname="solr.hdfs.home">${solr.hdfs.home:}</str>
<strname="solr.hdfs.confdir">${solr.hdfs.confdir:}</str>
<strname="solr.hdfs.blockcache.enabled">${solr.hdfs.blockcache.enabled:true}</str>
<strname="solr.hdfs.blockcache.global">${solr.hdfs.blockcache.global:true}</str>
</directoryFactory>
-->
<directoryFactoryname="DirectoryFactory"
class="${solr.directoryFactory:solr.NRTCachingDirectoryFactory}"/>
<!--
编解码工厂允许使用自定义的编解码器。例如：如果想启动per-fieldDocValues格式,可以在solrconfig.xml里面设置SchemaCodecFactory：
docValuesFormat="Lucene42":这是默认设置，所有数据会被加载到堆内存中。
docValuesFormat="Disk":这是另外一个实现，将部分数据存储在磁盘上。
docValuesFormat="SimpleText":文本格式，非常慢，用于学习。
定义的格式的CodecFactory反向索引。SchemaCodecFactory默认实现,这是官方的Lucene指数格式,但挂钩的模式提供域定制
帖子列表和每个文档的值在fieldType元素(postingsFormat/docValuesFormat)。注意,大多数的替代实现
实验,所以如果你选择定制索引格式,它的好想法通过IndexWriter.addIndexes转换回官方格式如(IndexReader)
升级到新版本之前,以避免不必要的改变符号。
当指定ManagedIndexSchemaFactory作为Solr为加载的模式。他在“managedSchemaResourceName”资源命名,而不是schema.xml。
注意,资源不能叫schema.xml管理模式。如果管理模式不存在,Solr将创建它在阅读模式。xml,然后重命名”模式。xml的“schema.xml.bak”。
不要手动编辑管理模式――外部修改将被忽略和覆盖的模式修改RESTAPI调用。
当指定ManagedIndexSchemaFactory可变=true,模式RESTAPI调用将被允许修改,否则,错误响应为这些请求返回。

<!--
设置索引库的锁方式，主要有三种：
1.single：适用于只读的索引库，即索引库是定死的，不会再更改
2.native：使用本地操作系统的文件锁方式，不能用于多个solr服务共用同一个索引库。Solr3.6及后期版本使用的默认锁机制。
3.simple：使用简单的文件锁机制
-->
<lockType>${solr.lock.type:native}</lockType>
<!--
是否启动时先解锁
如果这是真的,开启任何写或提交锁在启动时举行。
这违背了安全锁定机制,允许多个进程访问一个lucene索引,并且应该小心使用。默认设置是“false”。
这是不需要如果锁类型是'single'

提交删除策略
可以指定自定义删除策略。类必须实现org.apache.lucene.index.IndexDeletionPolicy。

<!--
设置索引库更新日志，默认路径为solrhome下面的data/tlog。随着索引库的频繁更新，tlog文件会越来越大，
所以建议提交索引时采用硬提交方式<autoCommit>，即批量提交。
-->
<updateLog>
<strname="dir">${solr.ulog.dir:}</str>

<!--自动硬提交方式
maxTime：设置多长时间提交一次maxDocs：设置达到多少文档提交一次openSearcher：文档提交后是否开启新的searcher，
如果false，文档只是提交到index索引库，搜索结果中搜不到此次提交的文档；如果true，既提交到index索引库，也能在搜索结果中搜到此次提交的内容。
提交自动在一定条件下执行困难。
启用自动提交,而是考虑使用“commitWithin”当添加文档。
maxDocs-最大数量的文档添加自上次提交之前自动触发一个新提交。
maxTime――最大的时间以来，可以通过文档添加之前自动触发一个新提交。单位ms
opensearch――如果错误,提交导致最近的指数变化刷新到稳定的存储,但不会导致一个新的搜索器被打开,使这些变化明显。
如果启用了updateLog,那么强烈建议有一些很难自动提交日志大小限制。
-->
<autoCommit>
<maxTime>15000</maxTime>
<openSearcher>false</openSearcher>
</autoCommit>
<!--
软提交VS硬提交：只要其中一个
softAutoCommit就像autoCommit除了它会导致一个“软”提交,只有确保变化是可见的,但不保证数据同步到磁盘。
这是更快和更接近实时的友好比硬提交。
-->
<autoSoftCommit>

更新相关事件监听器：
各种IndexWriter相关事件可以触发听众采取行动。
postCommit――每次提交或优化命令之后
postOptimize――每一个优化命令后
RunExecutableListener执行外部命令从一个钩postCommit或postOptimize等。
exe-运行可执行文件的名称
dir-dir作为当前工作目录。(默认=“.”当前目录)
wait-调用线程等待等到可执行的回报。(默认="true")
