Solr.xml

Solr對於index的管理是基於Core的概念的，Solr底層是經過lucene來進行index的，每個邏輯上的要index的業務對象均可以看做是一個core.

<solr persistent="true" sharedLib="lib">
 <cores adminPath="/admin/cores">
  <core name="core0" instanceDir="core0" />
  <core name="core1" instanceDir="core1" />
 </cores>
</solr>

The <solr> tag accepts two attributes:

• persistent - By default, should runtime core manipulation be saved in solr.xml so that it is available after a restart.

• sharedLib - Path to a directory containing .jar files that are added to the classpath of every core. The path is relative to solr.home (where solr.xml sits)
